Hello everyone,
I am performing full-text-search on a table containing word documents
in it's column. The search results fair when a single word is
searched. i.e. when I fire the following query:
select * from docs where contains(document, '"java"');
but if I try to search the a full line or give multiple words in the
text to be searched, then it shows no results, even if there is same
text present in the document stored in the database.
select * from docs where contains(document, '"this text is in
database"');
what could be the possible cause of the problem. Shouldn't the FTS
return the records which contains even a single word in the queried
text.
Please help me with the issue.
Thanks & Regards,
Varun Narang.
It definitely should return results for both a single token or a phrase.
However in your phrase you have noise words? Did you empty your noise word
list and replace it with a single space?

Because you have double quotes around the phrase, it will only look for rows
with that exact phrase in the text. If you want to search for any/all words
in any order and not necessarily in a single phrase, you need to remove
those double quotes. Also check BOL for the use of logical operators.
