Subject Re: fq parameter with partial value
Date Thu, 28 Apr 2011 12:36:53 GMT
So, I assume your CATEGORY field is multiValued but each value is not
broken up into tokens, right? If that's the case, would it work to have a
second field CATEGORY_TOKENIZED and run your fq against that
field instead?

You could have this be a multiValued field with an increment gap if you wanted
to prevent matches across separate entries and have your fq do a proximity
search where the proximity was less than the increment gap....

Best
