Hi Team - I am using Oracle Text in one of my project using Lexers and Multi_column datastores. I'm facing some problem with reserved words like "and", "or", "not", "near", "within" etc. Is there any way I can ignore them within Contains query or If I can just disable their native behaviour?

SELECT * FROM CATEGORIES
WHERE CONTAINS(CATEGORYNAME, 'AND', 1) > 0

SELECT * FROM CATEGORIES
WHERE CONTAINS(CATEGORYNAME, 'OR', 1) > 0

SELECT * FROM CATEGORIES
WHERE CONTAINS(CATEGORYNAME, 'ANY OTHER SENTENCE ENDING WITH A RESERVED WORK LIKE AND', 1) > 0


Thanks,
Raman

There are various things that you could do. For example, you could use the REPLACE function to remove those words from your search string or you could escape the words by enclosing them within { and }, causing them to be treated as regular text, instead of reserved words.

Thanks for replying, Barbara. That makes complete sense what you suggested. But what could be the reason that reserved words are not indexed?
