Subject Re: Get matched Term in join query
Date Tue, 09 Dec 2014 22:47:29 GMT
Hi,

Your question is a good one - I have added an option to search through
results and filter that way, but it's not ideal, as very often there are
10,000 or millions of hits, with only 20 results per page returned.

I've realized I run into the classic 'Terms-can't-filtered' issue. To
filter Terms would, in the worst case, mean looking up a great many items.
For now, I'm going with the TermsComponent added to the standard
searchhandler. The drawback is you get back all terms that match the
terms.regex, even those not necessarily in the results.

Many thanks,
Peter
