Thanks in advance!

insert into tb_class ('cadfecc', 'Paris'); commit;

Start
ctx_ddl.set_attribute ('STEM_FUZZY_PREF', 'FUZZY_MATCH', 'FRENCH'); ... It is only for the French?
end;

create index class_nm_idx on tb_class (nm) indextype is ctxsys.context parameters ("list STEM_FUZZY_PREF sync (on commit)" ");

Select * from tb_class where contains (nm, 'cadfcc', weight)', 1) > 0;

  2    (nm    varchar2 ( 20),
  3       addr  varchar2 (200))

    Hi, we need fuzzy search on the table who have 20 million records and willingness to develop continually add 20 K records every day. Our application is J2EE env where we do a jndi call to the database and run queries. Fuzzy search question what we have is the query to look EO_Short_Name similar as TestName and returns, as it scans the entire table taking a long time to retrieve the records of 20 TR_Details table.

    SELECT tt. TRADER_D                                                                 FROM pp.TR_DETAILS TDMESSAGE                                                                    WHERE                                                                 UPPER(TDMESSAGE. EO_SHORT_NAME) LIKE '% TestName % '.

    The table above have record 20 and we'll be adding K records 20 every day. Can someone approach the tips that we can follow to solve the problem above for large data...

    Thanks in advance

  • Fuzzy search help (does not work if change the order of some 2 letters)

    Hello

    need help with search fuzzy. It's pretty simple - we use fuzzy search on varchar2 columns that contain the name and name. The problem is that I don't really understand why she can't find the name in some cases.

    I want to get "Taekpaul". Then

    where CONTAINS (first_name, 'fuzzy (TAEKPAUL)', 1) > 0 - work
    where CONTAINS (first_name, 'fuzzy (TAEKPALU)', 1) > 0 - works (amended order to the last 2 letters)
    When CONTAINS (first_name, 'fuzzy (TEAKPAUL)', 1) > 0 - does not work, see "Brahim" is completely different (changed to the 2nd and 3rd order)

    How can I find 'Taekpaul', even if I get TEAKPAUL? Is she related to the index? As the text index must be created with different settings?

    Thank you!

    Hello

    I tried you have case, and I get the same results. I also tried with the soundex function "!" and gives me the result, so I tried this:

    where CONTAINS(first_name,'fuzzy(!TEAKPAUL)',1) > 0

    The difference is the "!" in front of the searchterm. Is this really the solution to your problem?

  • Multilingual (English, Portuguese, Chinese) façade panels

    I am looking for assistance with the taking of a program (written in LV 8.5.1) which can currently load languages from a file of text CSV (currently English and Portuguese) and add the ability to load also Chinese text.

    I have a written routine that parses the location CSV file (each column is a full-fledged language).  Then I go through each line and load the correct column in its respective place (captions for text entry, Boolean text for buttons) by program (Boolean text because you can't click through legends).  I found the thread of foreign language in Labview and have been able to copy and paste text in Chinese in the ActiveX control while the application is not running.  I was not able to use reading text file VI to import this text successfully.

    Does anyone have an idea how I would be able to import these data into LabVIEW?

    OlderJohn-

    I looked at your code and discussed this issue with some of my colleagues.  LabVIEW does not support Unicode, and this may be a case where it is not working properly.  I found an Article in the Knowledge Base that can be useful to help get this working (link below).

  • Search for text in the option in Windows Search 4.0 Preview pane doesn't work do not

    I use XP SP3.  I recently downloaded Windows Search 4.0.

    When the Windows search results window opens, I noticed that it is possible to search for text in the preview pane.  I click on a file and go to OPTIONS > COMPONENT of VISUALIZATION, but see that FIND is grayed out and unavailable.

    This function worked before, when I loaded Windows Search first; now, it no longer works.  My files have been fully indexed; and I made no changes to the computer since then.  I tried to restart the computer, but there was no change.

    Any ideas? Matthew W. I. Dunn

    Hello Matthew w. I. Dunn, welcome.

    I recommend trying a system restore to see if that solves the problem. Try this:
    1. click on START
    2. click on "all programs".
    3. click on "Accessories".
    4. click on "system tools."
    5. click on "system restore."
    6 follow the prompts shown to restore your system to a date before the problem started. Although the system restore does not target the personal data, it is recommended that you back up all data such as music, photos and documents in case something is not bad.

  • Search for text on a Web page in ModernUI IE10

    Is there a way to search for text on a Web page in the version of the modern UI for IE10?

    If you use modern IE, the shortcut must be identical to it in most web browsers:

    CTRL + F
    So, open IE, select a text field that opens the keyboard on the screen, then tap on and hold down the Ctrl key and press F release both. You should see a little extra box we pop that is your field of research to this page.

  • Is it possible to search for text in an Illustrator file from an external source like the Finder (Mac)?

    I'm trying to find some similar text strings on hundreds of files.  Specifically, I'm looking for dimensions.  4.50 "for example.  I want to see how many files have this dimension within them so that I can group them for production purposes.

    Is there a way to search for text in Illustrator (I use CS5) files from Finder?  Or another program of research?  I use a Mac.

    Any help would be GREATLY appreciated and would help save me a lot of time.

    Yes. While the Finder cannot find the content of .ai files, it can do it with .pdf files. If you change the extension of a .ai in .pdf file, you can use Spotlight to search by content.

    This fact, combined with a file rename utility as A Better Finder Rename, you can leave temporarily rename all of your .ai files so they end up in something like 'RENAMED.pdf '. Then, once you have performed your search, find all files ending in RENAMED.pdf, to delete the word "RENAMED" and change the end for .ai again.

    Of course, this isn't something you want to get into the habit of doing.

  • How to find / search the text in a table of data displayed in adobe flash player?

    I have a table of data displayed on the browser, but with Adobe Flash Player UI technology. CTRL + f does not work on the table to find a specific word in the table.


    What are alternates, you ask? or all the other shortcuts are available to search or search the text in such a case?

    Thank you.

    There is no good workaround solution.  The developer would have needed to implement a similar feature in their Flash application, or they would have needed to use StageText (which essentially exposes the native textfields), but it seems that they have neither.  The HTML TextField is certainly more robust and functional of the Flash, and honestly, HTML is probably a better choice of technology for what you describe.

    Mike,

    Oracle Enterprise R does not include the extraction of specific text features, but because it can exploit data in extraction of features Oracle database, it may inherit the ability to analyze textual data using the tm or other related packages of NOTCH. We provide examples of use of packages open source R with ore in the Oracle Enterprise of R User Guide and training materials. Here are some links to help you:

    See the section called "Run R calculation in Oracle Database":

    http://docs.Oracle.com/CD/E11882_01/doc.112/e36761/using.htm#OREUG163

    See slide 25:

    http://www.Oracle.com/technetwork/database/options/advanced-analytics/r-Enterprise/ore-trng3-transprncylayer-1501636.PDF

    Any R package used with ore must be installed with the R on the database server and client of R.
