Chris Morley here, from Wayfair. (Depahelix = my domain) Suyash Sonawane and I have worked on multiple word synonyms at Wayfair. We worked mostly off of Ted Sullivan's work and also off of some suggestions from Koorosh Vakhshoori. We have gotten to a point where we have a more sophisticated internal implementation, however, we've found that it is very difficult to make it do what you want it to do, and also be sufficiently performant. Watch out for exceptional situations with mm (minimum should match).
Trey Grainger (now at Lucidworks) and Simon Hughes of Dice.com have also done work in this area. It should be very possible to get this kind of thing working on SolrCloud. I haven't tried it yet but I think theoretically, it should just work. The synonyms stuff is mostly about doing things at index time and query time. The index time stuff should translate to SolrCloud directly, while the query time stuff might pose some issues, but probably not too bad, if there are any issues at all. I've had decent luck porting our various plugins from 4.10.x to 5.5.0 because a lot of stuff is just Java, and it still works within the Jetty context. -Chris. ---------------------------------------- From: "John Bickerstaff" <j...@johnbickerstaff.com> Sent: Thursday, May 26, 2016 1:51 PM To: solr-user@lucene.apache.org Subject: Re: Solr Cloud and Multi-word Synonyms :: synonym_edismax parser Hey Jeff (or anyone interested in multi-word synonyms) here are some potentially interesting links... http://wiki.apache.org/solr/QueryParser (search the page for synonum_edismax) https://nolanlawson.com/2012/10/31/better-synonym-handling-in-solr/ (blog post about what became the synonym_edissmax Query Parser) https://lucidworks.com/blog/2014/07/12/solution-for-multi-term-synonyms-in-lucenesolr-using-the-auto-phrasing-tokenfilter/ This last was useful for lots of reasons and contains links to other interesting, related web pages...
