Unanswered: I have problem in searching BLOB field that store word document.
Hi,everyone,I need your help.
I create a table that contains a BLOB field and create index(CTXSYS.CONTENT) on the BLOB field.Then I insert a MSWORD documents into it and test it.
There ,the name of index is MYINDEX,I execute the following SQL statement:
SELECT TOKEN_TEXT FROM DR$MYINDEX$I;
When I insert plain text file(.txt) that in Chinese,It is normal ;MSWORD in ENGLISH ,it is normal too.But when I inserted MSWORD in CHINESE,the result of that SQL statement is not normal:some words is correct Chinese words but some of them is bad word (not recognized).
I use chinese_vgram_lexer and use custom filter whose charset is set "ZHS16GBK", NLS_LANG is "ZHS16GBK" too.
