Adding debugQuery=on can give you some more information like how the score for a particular document was calculated for the given query. > 2 - Can solR make analysis on an index to extract associations between > tokens ? > > for example , if "foo" often appears with "fee" in a field, it will > associate the 2 tokens. > > Solr won't compute associations but there are ways of achieving something similar. For example, the MoreLikeThis functionality clusters related documents through co-occurrence of terms in a given field. Also, the TermVectorComponent can give you position information for terms in a document. You can use that to build your own co-occurrence associations. If you just want to query for two words within a fixed position difference, you can do proximity matches. http://lucene.apache.org/java/2_9_0/queryparsersyntax.html#Proximity%20Searches Perhaps somebody else can weigh on your question #3 and #4. -- Regards, Shalin Shekhar Mangar.
