> Here's a patch that implements simple support of Lucene's MoreLikeThis class.
> The MoreLikeThisHelper code is heavily based on (hmm..."lifted from" might be
> more appropriate ;-) Erik Hatcher's example mentioned in
> http://www.mail-archive.com/[EMAIL PROTECTED]/msg00878.html
> To use it, add at least the following parameters to a standard or dismax
> query:
> mlt=true
> mlt.fl=list,of,fields,which,define,similarity
> See the MoreLikeThisHelper source code for more parameters.
> Here are two URLs that work with the example config, after loading all
> documents found in exampledocs in the index (just to show that it seems to
> work - of course you need a larger corpus to make it interesting):
> http://localhost:8983/solr/select/?stylesheet=&q=apache&qt=standard&mlt=true&mlt.fl=manu,cat&mlt.mindf=1&mlt.mindf=1&fl=id,score
> http://localhost:8983/solr/select/?stylesheet=&q=apache&qt=dismax&mlt=true&mlt.fl=manu,cat&mlt.mindf=1&mlt.mindf=1&fl=id,score
> Results are added to the output like this:
> <response>
> ...
> <lst name="moreLikeThis">
> <result name="UTF8TEST" numFound="1" start="0" maxScore="1.5293242">
> <doc>
> <float name="score">1.5293242</float>
> <str name="id">SOLR1000</str>
> </doc>
> </result>
> <result name="SOLR1000" numFound="1" start="0" maxScore="1.5293242">
> <doc>
> <float name="score">1.5293242</float>
> <str name="id">UTF8TEST</str>
> </doc>
> </result>
> </lst>
> I haven't tested this extensively yet, will do in the next few days. But
> comments are welcome of course.
