Hello Kunal,
The syntax of free-text queries is described in details in
http://docs.openlinksw.com/virtuoso/queryingftcols.html#textexprsyntax
Free-text is capable of looking weaker that an exact phrase but has no way to
get more strict filtering. So you may start with bif:contains and additionally
provide "like" operator in the filter. In this case free-text may work fist and
provide a list of "more or less appropriate" hits and the filter will deal with
short "appropriate list", not with everything.
Best Regards,
Ivan Mikhailov

Subject: Re: [Virtuoso-devel] bif:contains
Thanks Hugh,
The quotes work. Also is there a way to do exact matches with
bif:contains, for example a query to get all the people whose name is exactly
"jack jill".

Hi Kunal,
The following query should work:
select *
from <people>
where {?s foaf:Name ?name . ?name bif:contains "'jack jill'" .}
Note the addition of single quotes within the double quotes which is how we
handle phrases in bif:contains.

Hi,
How can I use bif:contains predicate for a string value with multiple
words. For example when I run the following query it works fine,
select *
from <people>
where {?s foaf:Name ?name . ?name bif:contains "jack" .}
But trying to run the query below doesn't work.
select *
from <people>
where {?s foaf:Name ?name . ?name bif:contains "jack jill" .}
