Hello Lee, these bells sound like "SKOS" ;o)
AFAIK Solr does not support thesauri just plain flat synonym lists. One could implement a thesaurus filter and put it into the end of the analyzer chain of solr. The filter would then do a thesaurus lookup for each token it receives and possibly * expand the query or * kind of "stem" document tokens to some prefered variants according to the thesaurus Maybe even taking term relations from thesaurus into account and boost queries or doc fields at index time. Maybe have a look at http://poolparty.punkt.at/ a full features SKOS thesaurus management server. It's also providing webservices which could feed such a Solr filter.

Does SOLR have a thesuarus. Cant find any refrerence to one in the docs and on the wiki etc. (Apart from a few mail threads which describe the synonym.txt as a thesuarus) I mean something like: PT: xxxx BT: xxx,xxxx,xxxx NT: xxx,xxxx,xxxx RT:xxx,xxx,xxx Scope Note: xxxxxx,xxxx Like i say bells and whistles cheers Lee
