Hi,
I was wondering if there's an option to return statistics about distances from the query terms to the most frequent terms in the result documents. At present I return the most frequent terms using facetSearch which returns for each word in the result documents the number ob occurences (within the results). The additional information I'm looking for is the average distance between these terms and my search term. So let's say I have two docs "the house is red" "I live in a red house" The search for "house" should also return the info the:1 is:1 red:1.5 I:5 live:4 and so on... As I wasn't able to find such a function I thought about two solution for the problem 1) Use facetSearch and implement a different facet.method which calculates the average distance of a word to the given search term. Solr doesn't seem to provide an interface to implement a different method so I think this solution would be a bit dogdy and would lead to problems with the next Solr Upgrade. 2) Using the TermVectorComponent which return the position of each word within a document, I could calculate the distance based on this data in the application. But TermVectorComponent returns information per document which means I would need to return all documents of the result set which is probably not recommended. My question is a) Did a miss a function of Solr that already does what I'm looking for? b) Is solution 2) feasible even if I always have to return all docs of the results set (the content doesn't need to be return though, just the statistics) c) Are the interfaces to ammend facetSearch the way I described which I might have missed? Thanks Jens
