  It works if you put a clause of additional PARAMETERS to the end, so the creation looks like:

• Oracle Text, multi_column_datastore describe index

  Referring to the Re: Oracle Text, ctxsys.context problem with column number
  
  TOAD or SQL Navigator, you can click on an object any (such as a table, index) and click on the "script" tab where the code is generated to create.
  
  Assuming that I am a person who sees the index for the first time where/how I can find multi_columns/settings with which the index has been created?
  
  For example:

  exec ctx_ddl.drop_preference( 'myds' );
  exec ctx_ddl.create_preference( 'myds', 'MULTI_COLUMN_DATASTORE' );
  exec ctx_ddl.set_attribute( 'myds', 'COLUMNS', 'item_barcode, item_title, item_subtitle' );
  CREATE INDEX i_index_test
     ON item (item_title)
     INDEXTYPE IS ctxsys.context
     PARAMETERS ( 'datastore myds' );

  And script says:
  

  CREATE INDEX PLSQL.I_INDEX_TEST ON PLSQL.ITEM
  (ITEM_TITLE)
  INDEXTYPE IS CTXSYS.CONTEXT
  PARAMETERS('datastore myds')
  NOPARALLEL;

  Where can I find datastore "myds"?

  You can use ctx_report to get information about an index.

  I use it for SQL * more like this:

  set pagesize 0
  set heading off
  set trimspool on
  set long 500000
  
  spool index.sql
  
  select ctx_report.create_index_script('MyIndexName') from dual;
  
  spool off
  

  The only thing it will not give you is the source for all of the procedures used in the user_datastore. You can get to user_sources.

• Problem indexing Oracle text

  Hi all
  
  We have recently migrated one of our database to oracle 10.2.0.2 to Oracle 10.2.0.4 and since that time, Oracle Text Engine an indexer is unable to work properly.
  
  Indexing data systematically result in the following error:
  DRG-50857: error oracle in dreii0fsh
  ORA-06550: line 1, column 106:
  PLS-00302: component 'S_MODE' must be declared.
  ORA-06550: line 1, column 10:

  Note that the data that have been indexed with the previous Oracle version can still be found with ' Select... where... contains. ', although new datas not indexable at all.
  
  Can someone help me with this problem?

  See on metalink:

  "DRG-50857: oracle in dreii0fsh error ' when creating indexes of TEXT [750898.1 ID]"

  It seems that you updated the binaries, but Oracle not the text itself.

• Big problem with Oracle Text

  Hi all
  I use the Oracle text to perform a full text search. I have my column indexed like that
  
  CREATE INDEX cm_property_text ON cm_property (text_value) INDEXTYPES IS CTXSYS. FRAMEWORK
  
  After that, I inserted a line in the text_value field have contain is: "I and you or other ', then run the synchronous command my index finger:
  
  Begin
  CTXSYS. CTX_DLL. SYNC_INDEX ('cm_property_text');
  end;
  
  Then I run the query to select out have the text_value line contains text value is "I and you".
  
  SELECT * FROM cm_property WHERE CONTAINS (text_value,' I / you "")
  
  But I got nothing. And I tried to change like this looking for text entry
  
  SELECT * FROM cm_property WHERE CONTAINS (text_value, ' I/you and/or other "" ");
  
  And I had a line that is the line that I inserted before.
  
  I have really no why? Who can help me to explain about this?
  
  Thank you very much!

  If you want to be able to search for empty words by default, you can use an empty stopwords list or which does not contain the words you want to search. For a single character escape, preface with-not. To escape a whole word or phrase, such as a keyword or reserved word, surround it with {}. Please see the demo below.

• Problem with the Oracle text markup

  Hello
  
  I have a problem with the Oracle text markup.
  
  I am looking for keywords in a text which is composed by a question and answer.
  Here is the structure of my text:
  & lt; div class = 'question' & gt;
  & lt; a & gt; the title of my question & lt; /a & gt;
  & lt; div class = "reply & gt;
  content of response
  & lt; / div & gt;
  & lt; / div & gt;
  
  It is possible to search those keywords in the question or answer only. For this, I use the stored procedure:
  
  {call CTX_DOC. MARKUP)
  index_name = >?
  textkey = >?
  text_Query = >?
  restab = >?
  query_id = >?
  startTag = >?
  (EndTag = >?)}
  
  _with these parameters: _
  
  index_name = < my index >
  textkey = < id for the search text >
  text_Query = < a query containing the keywords >
  restab = < a table SQL to store the marked text >
  query_id = < id >
  startTag = ' < span class =-"highlight\" >. "
  EndTag = "</span >.
  
  The markup should be done only in the place you want (question, answer, or both).
  The markup is good when I search a keyword throughout the text, in the question or answer only.
  * If I search two key words in the question or answer, the markup is bad *.
  
  _Example: __
  I am looking for the words "* Internet *" in question only.
  Here's the query passed to the stored procedure:
  + * text_query * = 'service & internet' INPATH (//div[@class = 'question'] / has) +.
  
  In the question, these words are well marked.
  In response, only the first word is marked.
  
  * Why the first keyword is also marked in the response while the query specifies a search in question only? *
  
  The same problem appears when I search for the same keywords in the response only.
  In this case, in the answer, these words are marked as well.
  In the issue, only the first word is marked.
  
  Thanks for your help
  
  Edited by: user11088931 Apr 21. 2009 06:17

  Try text_query = (service & internet) INPATH (//div/a)

  Single quotes in a query do nothing. I think that your request has been treated as

  Service & (internet INPATH (//div/a))

• Oracle text index - unexpected behavior

  We have a SEARCH_TABLE (in Oracle 12.1.0.1.0) with a couple of files (actually about 10,000,000 records):

  ID ADDRESS

  1     | WIMPEL | 57. 9733BK | GRONINGEN |

  2     | JOHAN WILSSTRAAT | 7 ||| 1333PV | ALMERE |

  3     | ABRAHAM KUYPERHOF | 10. 8091XN | WEZEP |

  
  

  To support research on the table addresses, we apply an Oracle text index:

  create index ST_CTX1 on SEARCH_TABLE (address)

  indexType is ctxsys.context

  parameters ("DATASTORE CTXSYS. DEFAULT_DATASTORE');

  
  

  Our research focuses on whole words (without jokers). When searching through the data, it usually comes back with the correct results.

  
  

  SELECT THE ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, 'GRÖNING') > 0

  ;

  Returns nothing, that is correct. Once the search argument 'GRÖNING' is replaced by 'GRONINGEN', ID 1 is correctly selected. According to this behavior, the following query returns no records:

  SELECT THE ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, 'ABR & KUYPERHOF') > 0

  ;

  
  

  Surprisingly, however, the following query returns record ID 3:

  SELECT THE ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, ' A & KUYPERHOF ') > 0

  ;

  (Even if data does not contain the complete word 'A'). This unexpected behavior only seems to occur when you use "A" as the initial character.

  The following query (with the search starting with the character 'J' argument) returns no data. Which is the expected behavior.

  SELECT the ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, 'J & WILSSTRAAT') > 0

  ;

  Anyone has an idea why the text index returns with A situations? Any ideas on how to solve this problem are appreciated.

  Mark

  According to the list of empty words by default in 11.2, the letters a, d, i, s, and t are listed, so would be removed from the wanted list of tokens.  Thus, 'A & WILSSTRAAT' becomes '& WILSTRAAT' and search text line with a single word.  'j' is not an empty word, so it is considered to be a token is valid and is not in your tables.  Look in CTXSYS. CTX_STOPWORDS to see what you have.

  It helps if you post a copy and paste of effective enforcement of the full code, including the results.  You posted an index of context with the query with catsearch, which requires a ctxcat index.  You must be a context clue that you did not post and did not add your lexer to.  The following table shows it returns all the lines of 3 as planned using either a with catsearch ctxcat index or a context index with contains, as long that you include the lexer in your create index.  You must also be sure that the index is created, or synchronized after inserting or updating data.

• The abbreviated word Oracle text query / name

  I am new to Oracle text so please excuse the simple question (probably). I want to be able to create a search that excludes (including?) special characters or spaces between the short name. I don't know if it's possible, but I would like to be able to return all results below if an interviewee in 'ABC' under one form or another.
  
  It would be something that I would add a thesaurus? In my view, there is a list of EMPTY words, but I don't know if it is the opposite of a list of empty words.
  
  Thanks in advance!

  SELECT SCORE(1), id, text FROM docs WHERE CONTAINS(text, 'ABC', 1) > 0;

  Maybe it's that my SQL statement is not taking advantage of the text options - that is to say I forget something obvious :)

  The indexes are by default case insensitive, so let's ignore that.

  You can wal-mart and wal * mart match Wal-Mart by setting "-" and "*" as characters SKIPJOINS. However, you cannot not wal mart walmart match, otherwise than by the use of the NDATA.

  NDATA seems to work - any variation of wal mart Walmart wal * mart and wal-mart manage to match the Wal-Mart and wal-mart. See the example:

  SQL> create table testcase (text varchar2(2000));
  Table created.
  
  SQL> insert into testcase values ('walmart');
  1 row created.
  
  SQL> insert into testcase values ('wal mart');
  1 row created.
  
  SQL> exec ctx_ddl.drop_section_group('tcsg')

• Oracle Text missing words

  I have researched and received a different number of results. Can anyone explain why?
  
  Select * from table where upper (clobField) like ' % YEAR % ".
  
  Select * from table where contains (clobField, '% a %', 1) > 0
  
  When I perform the following search, I can see obvious CLOB which contain the required text, but is not returned to the oracle text search.
  
  Select * from table where upper (clobField) like ' % YEAR % "and does not contain (clobField, '% a %', 1) > 0
  
  I use a lexer base with all the default settings. Also, I can search on other words in the CLOB rejected that will come back them very well. Are the words that I found so far that I can't search on 'one' and 'who' and that's when I stopped in frustration. Thanks for any help!

  First of all, by the way, if you're looking for a whole word or a token, you don't need to use the wildcard '%' with Oracle Text.

  Second, text index Oracle using [url http://docs.oracle.com/cd/E11882_01/text.112/e24435/ind.htm#CIHCGIEA] lists of EMPTY words, for example http://docs.oracle.com/cd/E11882_01/text.112/e24436/astopsup.htm, which are intended to avoid indexing of low value words - the words you want normally to search. If you want to index these then you can disable the list of stopwords. Your indexes bigger of course.

• Oracle Text corresponds to unexpected lines

  Hi people:

  I use Oracle Text in Oracle 12 c to search the text for a column that is indexed as follows:

  We will examine these lines.

  • Table X

  Text
  90-SE
  90-BA
  Hello

  I want to search the text "90-SE", then I did the following SQL query:

  SELECT TEXT, SCORE (1)

  X

  WHERE CONTAINS (TEXT, '90\ - SE', 1) > 0;

  The result is:

  Score (1)	TEXT
  5	90-SE
  5	90-BA

  I can't understand why it is corresponding to the line containing 90-BA.

  Thank you

  ytor

  I am unable to reproduce your error, but I do not know what lexer attributes and others you may have.  I don't know if you are aware that unless you set the hyphen as a printjoin it is not indexed.  Please see the demo below, noting the differences in the token_text.

  Ed, I could just figure it out and I could actually find this solution everywhere else (thanks to Bogdan, a friend who recommended to check)

  The initPG_LINK.ora library was wrong and I dind´t had a simple way to find the right way:

  • I set the variable on my environment (there, I created a global file for odbc)

  export ODBCSYSINI=/etc
  

  • I tried to connect to the remote database to PostgreSQL with isql and it worked as well, the library was present.
  • Then, I checked on the isql libraries called< and="" this="" is="" probably="" the="" best="" way="" to="" avoid="" wasting="">

  [root@oracle ~]# which isql
  /usr/local/bin/isql
  [root@oracle ~]# ldd /usr/local/bin/isql
          linux-vdso.so.1 =>  (0x00007fffdff44000)
          libodbc.so.2 => /usr/local/lib/libodbc.so.2 (0x00007fa7ed96b000)
          libdl.so.2 => /lib64/libdl.so.2 (0x0000003184000000)

          /lib64/ld-linux-x86-64.so.2 (0x0000003183c00000)
  

  • I added this line (/ usr/local/lob/lobodbc.so.2) in the HS file.
  • Then, I added the ENVS with LD_LIBRARY_PATH setting to the location of the library

  SID_LIST_LISTENER=
    (SID_LIST=
      (SID_DESC=
        (SID_NAME=PG_LINK)
        (ORACLE_HOME=/u01/oracle/product/11.2.0.4)

        (PROGRAM=dg4odbc)
      )
    )
  

  A finally it worked!

  Thank you
