Thanks for your reply, I've attempted to use some of these plugins but ultimately I find that particularly if you are trying to improve relevancy, they fall apart. As an example when using the hon_lucene plugin, which works globally to expand synonyms across your entire query, if you are trying to do phrase boosting, it results in a single word query term that has multi-term synonyms having matches for the synonyms that are artificially boosted above ones with the search term that was entered. Not good. This right now has ended up being the number one issue for us in achieving the relevancy results we need on Solr so it was really frustrating to not see it even mentioned, let alone a viable solution. It's particularly frustrating to find out how long it has been an issue in Solr and yet not addressed.
