The wildcard search

Blocks the im trying to a lookup field in a database of a block no DB and if I type in what is exactly the value of the field, nothing returns. I have a field that can hold up to 2000 characters and I want to be able to search by keyword...% did not work for me...

You would still have the % in the database-user field no it is entered. You could even encapsulate field '%' when you set your v_where clause:

v_where: = 'like % | : nondatabaseblock.field | '%';

I did similar things to this, but you should keep in mind when you use AS you end up doing full table scans which can slow down the Application if the table is large enough.

  • Short: activate the wildcard search

    Hello world

    I have an Oracle Linux 6.6 3 components installed:

    -Oracle short Server 7.6.1

    -Oracle short discovered Information Integrator 3.1.1

    -Oracle short Information discovered Studio 3.1.0

    I'm sorry if this is too newbie...

    I want to activate the on an attribute wildcard search to locate text in the middle of words (for example, * in * would correspond to 'find').

    I found a page with a few tracks: http://docs.oracle.com/cd/E40518_01/server.761/es_dev/toc.htm#Configuring%20wildcard%20search%20in%20record%20search

    However, I don't know how to proceed. This page shows an example of use of a web service request (' soap: envelope "). You could point me please in the directions? Do I have to create a graph, adding components "Universal Data Reader" and "Web Service Client"?

    I'm sorry if the question seems vague, but I am a bit lost...

    Thank you

    Fausto

    Dear Fausto,

    You have found the necessary information and are very near doing this task. You are also right in the doc, while we provide information on the level of WEb Services, it not there no procedure end-to-end in the Integrator user's Guide. The reason for this is because this procedure relies on the use of the standard Integrator component (not a component EID created). The component that you can put in the Integrator to send in the XML graph is called Web Services Client.

    Below, I describe the steps.

    Context:

    To activate the search by wildcard characters, you must set the schema property for the configuration of indexing to true. It's the mdex-property_TextSearchAllowsWildcards. Must be true for the wildcard search is activated.

    This property is one of several properties on the GCR (record of the Global Configuration), which is used by the indexes of the Dgraph.

    To change this property, there are several ways: using SOAPUI, or graphic Integrator with the Web Services Client component. The two methods are described below.

    1. with the help of SOAP UI for the Web Service of Config for the loading of the DGC (Configuration global registry, which is an XML document)

    You can use any Web Service, such as SOAP UI user interface tool and that it points to the Dgraph running. In this document, you can access the Configuration Web Service with this URL:
    : /short-server/ws/config / ? wsdl (this is documented on the "On the Web Service Setup").

    Then, you can send the RCMS of together again to the Dgraph, using the putProperties of the Config Web Service operation. See this topic for info; It uses the same operation for the addition of configuration XML documents: load the schema of attribute

    Then, in the SOAP UI, you can issue a query similar to the following:

    <>

    "xmlns:config ="http://www.endeca.com/MDEX/config/services/types/3/0"

    xmlns:MDEX ="http://www.endeca.com/MDEX/config/XQuery/2009/09" >. "

    true

    2 using the Integrator and its graph based on XML, for loading XML documents. For info, see this topic and some subjects beneath him.

    The Integrator user's Guide > data domains configuration > Global Configuration record, you will see that this implies essentially to create a chart that uses a Web Services Client (it is a component of standard clover you can use), to load the same RCM document that you free of charge if you use SoapUI.

    For the WebServiceClient component, specify a string similar to the following in the name of the component operation field:

    {http://www.endeca.com/MDEX/config/services/config/3}Config#ConfigPort#DoConfigTransaction
    

    Notice that this string includes a namespace target for the Web service that faithfully reflects the major Web service as version / 3 in this example (you must have this web service as version 3.0 too, but please check what version of the WS Config you use.) In the Installation Guide for server short 7.6.1 you can see how to check it: list of Web Services of short and their versions

    I hope this helps!

  • How to restrict the wildcard character in the search form?

    Hello
    I am new to ADF and learning from Steve's blog. I was going to for example 158th in which he restricted the wildcard search. I could not

  • How to force the Explorer search to show ONLY the files that match the search target?

    I frequently need to search for files with brackets in the name of the file.    However, a bug in the Search Explorer means that search results will fill up with a lot of waste that does not match my search target.

    Example:

    At a command prompt "dir/s * (abc) *.» ' * ' usually works: the name of each file found will contain "(abc)".   (The only time that a search for the command line fails is when the version 8.3 of the name of the file matches the search target, but the name of the actual file does not work.)

    However, in Solution Explorer, look for "* (abc) *.» "*" returns all files with 'abc' in the name, and provides no way to filter the results so that I only see files with '(abc)' in the name of the file.

    This search bug means that you want "* (de) *.» ' * ' at the command prompt returns 72 hits, while searching with Explorer returns 7381 hits!

    Cancellation: Another inconvenience of Windows is when I work at a command prompt I get often unexpected results because the wildcard matching is done against both the full name of the file or folder and the name of 8.3.   Is there a way to force cmd.exe to restrict the wildcard matches only the complete names of the files and folders?  That is to say, is there a way to force cmd.exe to never, ever, use the 8.3 names?

    Hi Rob,

    In order to quickly provide a solution, please answer this question:

    Did you do changes on the computer before the show?

    Follow the steps below to solve the problem:

    Method 1: If you have problems of location of the files, folders, or other items on your computer, try using the search and indexing of troubleshooting to solve the problem. It ensures that the Windows Search service is running and checks if you have the correct permissions to search all the directories on your computer.

  • performance of the 10g search text fuzzy

    Hello to all members of this community,

    IM new to this and I have a question that belongs to the Oracle 10g text.

    My configuration:

    Oracle Database 10 g Enterprise Edition Release 10.2.0.4.0 - 64 bit

    8 cores with each 2,5 GHz

    64 GB OF RAM

    What I would do:

    I would like to compare a large amount of games of lines between them so that human caused errors (e.g. spelling, typos) will not be tolerated.

    My setup of CONTEXT of the TEXT is as follows:

    MULTI_COLUMN_DATASTORE with each column to compare.

    begin
      ctx_ddl.create_preference('my_datastore', 'MULTI_COLUMN_DATASTORE');
      ctx_ddl.set_attribute('my_datastore', 'columns', 'column1, ...'); 
    end;
    

    BASIC_LEXER - with the parameters of the GERMANS:

    begin
       ctx_ddl.create_preference('my_lexer', 'BASIC_LEXER');
       ctx_ddl.set_attribute('my_lexer', 'index_themes', 'NO');
       ctx_ddl.set_attribute('my_lexer', 'index_text', 'YES');
       ctx_ddl.set_attribute('my_lexer', 'alternate_spelling', 'GERMAN');
       ctx_ddl.set_attribute('my_lexer', 'composite', 'GERMAN');
       ctx_ddl.set_attribute('my_lexer', 'index_stems', 'GERMAN');
       ctx_ddl.set_attribute('my_lexer', 'new_german_spelling', 'YES');
    end;
    

    BASIC_WORDLIST - with the parameters of the GERMANS:

    begin
       ctx_ddl.create_preference('my_wordlist', 'BASIC_WORDLIST');
       ctx_ddl.set_attribute('my_wordlist','FUZZY_MATCH','GERMAN');
       ctx_ddl.set_attribute('my_wordlist','FUZZY_SCORE','60'); --defaults
       ctx_ddl.set_attribute('my_wordlist','FUZZY_NUMRESULTS','100'); --defaults
       --ctx_ddl.set_attribute('my_wordlist','SUBSTRING_INDEX','TRUE'); --uncommented due to long creation time of index
       ctx_ddl.set_attribute('my_wordlist','STEMMER','GERMAN');
    end;
    

    And a BASIC_SECTION_GROUP with a field_section for each column.

    begin
      ctx_ddl.create_section_group(
        group_name => 'my_section_group', 
        group_type => 'BASIC_SECTION_GROUP'
      );
      ctx_ddl.add_field_section(
        group_name   => 'my_section_group',
        section_name => 'column1',
        tag          => 'column1'
      );
    ...
    end;
    

    I create the index with

    create index idx_myfulltextindex on fulltexttest(column1)
    indextype is ctxsys.context
    parameters ('datastore my_datastore 
                 section group my_section_group 
                 lexer my_lexer
                 wordlist my_wordlist 
                 stoplist ctxsys.empty_stoplist')
    

    Everything works well functionally.

    In my test scenario, I had a table with lines about 100,000 that has a primary key that is not in the CONTEXT index.

    The problem:

    I do a query like:

    SELECT SCORE(1), a.* 
    FROM fulltexttest a 
    WHERE CONTAINS(a.column1, 'FUZZY(({TEST}),,,W) WITHIN COUMN1', 1) 
      AND a.primkey BETWEEN 1000 AND 4000
    

    This will do a full text search in a set of 3000 lines. Here, the response time is almost immediate. Maybe a second.

    If I do the same in a slider repeatedly (> 1000) with various search terms, we take one of course a lot of time. It does in the average 1 requests per second.

    I thought that this cannot be that slow and I tested the same with:

    SELECT SCORE(1), a.* 
    FROM fulltexttest a 
    WHERE CONTAINS(a.column1, '({TEST}) WITHIN COUMN1', 1) 
      AND a.primkey BETWEEN 1000 AND 4000
    

    NOTE there is no fuzzy search more...

    With that, it is up to 20 times faster.

    The cpu of the server about 15% charge when the fuzzy query processing.

    So:

    If I do a fuzzy search, it seems do not access the index. I thought I was saying to the index to calculate the results of 100 extensions in advance.

    I'm doing it wrong? Or is it not possible to build a particular Index to the fuzzy search?

    Are there suggestions to improve performance? Note that I have already read the guide (7 Tuning Oracle Text). None caused advice cure.

    I would be grateful if anyone can help me in this case... Or simply to give an indication.

    Thank you

    The attributes of a list of words can be used to specify how developed the stems and fuzzies create prefix and substring index.

    If you do a lot of research with generic characters from end, like partialword % then a prefix index can make these quick searches.  If you do the research with two wildcard characters, such as % partialword % then an index of the substring can make this faster research.  There is a trade-off between taking time and storage space to create and maintain the index with prefixes and/or substrings and time of the query.  You can specify the minimum length of a prefix.  The shorter length, prefixes no longer possible and the longer it takes to create the largest index.  So you need to use depends on what types of queries you expect most of the time.

    I don't know if you have tested from queries.  The attribute index_stems of the lexer and the attribute of forms derived from the word list generator are in conflict.  You must keep the generator attribute of forms derived from the list of words and do not use the attribute index_stems of the lexer.

  • Default behavior of short wildcard search


    Hi friends,

    Is there a way to control the short wild-card as default search behavior when we search and if we "searchterm *", we get results for ' * searchterm * "but it is possible to restrict the result set so that it contains only" searchterm * ", we understand that it can be filtered at the code level, but we are looking for a way to do it in short itself.

    Inputs/suggestions are appreciated.

    Kind regards

    Shreyas

    Sarah,

    I'm a bit confused by your first sentence and would like to clarify.

    When you say a search on ' term * ' returns ' * term * "-you don't want to say something like ABCtermDEF being returned but rather ABC termDEF.»»

    Without the wildcard character in front of 'term', short does not return all the words that begin with anything else of "term".  Thus, it is the case, then you could check the reqlogs to see that something else is not inject the leading asterisk.

    So, if your use case so more like "I want to find all the records that have, as their first word, a word that begins with"term", then it is not supported without a little manipulator gyration.  In this case, I create a separate property called say 'AllFirstWords' and have a manipulator put all the first words in this property.  Then your search for these can go against that property.

    For example, if the original property was 'Draped Velvet' and you want to find "Vel * ' but not ' Dra *", and then with your new property which has just "Velvet" you are set.

  • Missing bookmarks in the smart search field in Safari

    Since the release of El Capitan 10.11.6, favorites are missing from the smart search field in Safari to new Windows.  If a Safari any page web (so far), clicking in the search box if poster is Favorites to view icons, as is expected.

    Is this a bug, or can I make some adjustments to bring them new windows?

    Thank you!

    Dick

    Hello Dick Huitema.

    If I understand your message to the right, when you open a new window in Safari, you do not see your favorite icons in the smart search field.  When I use Safari, I always like to have my favorites available and ready to use, so I can understand why you would be tender for assistance with this.

    You probably feel that if Safari is set to open new windows in an empty page. If yours is configured in this way, there is a very easy way to get these favorites icons to show without actually changing any settings. When you open a Web page, you should see a blank webpage with your top search bar and a cursor blinking in the search bar. Instead click inside the search bar right away, click anywhere on the empty Web page and then click on in the empty search bar. You should then see your Favorites icons appear.

    Another option is to set your homepage to your Favorites. You can do it in Safari > Preferences. On the general tab in Safari preferences, select the drop-down menu next to "new windows open with", and then choose favorite. This should ensure that when you open new web pages, all your Favorites icons show immediately. Favorites icons always appear in the smart search field when additional tabs are open as well.

    Here are a couple of really helpfuls articles on Safari Favorites and search options:

  • Can I get the Firefox search bar for not automatically, go to the site of the search engine I spend?

    The Firefox search bar seems to have changed since the last update. I understand that things are changing constantly and get used to them, but I wonder if it is possible to change the rear bar to the way it was, or at least understand why it changed.

    Basically, I used to be able to switch from search engines by choosing from the drop-down list, and would not put me right at the site of this search engine. He didn't actually bring me to the site once I hit the search button (or enter). It's quite annoying to have to remember to open a new tab before changing search engines in order to avoid sailing away from the tab that you are currently on, and it's also annoying that when you open a new tab and change the search engines, you are immediately taken to the site of this search engine. It feels like an extra step (ranging from 'the empty tab search engine page to search result' instead of 'empty tab to search result').

    I know it sounds like a minor complaint, no doubt, but I'm really really curious to know why it was changed. More important, I want to know if there is a way to customize the way it was.

    Thanks for any help!

    Many users have been raising this issue. I mentioned the same question in this post here: https://support.mozilla.org/en-US/questions/1086138

    In summary, it seems that the Firefox team is not intend to bring back the ability to return to the old bar search, which was possible (but in a very biased way) in older versions of 42. For now, you can either:

    • Download module additional classic restaurateur theme to https://addons.mozilla.org/en-US/firefox/addon/classicthemerestorer/?src=ss and then select the old search option
    • Go back to Firefox 42 and set the browser.search.showOneOffButtons property in Subject: config. However, with older versions poses a risk to the security that you won't have bug fixes provided with version 43
