: I may have not made myself clear. When I say keyword report, I mean a kind : of a most popular tag cloud, showing in bigger sizes the most searched : terms. Therefore I need information about how many times specific terms have : been searched and I can't see how I could accomplish that with this : solution....
you have to be more explicit about what you ask for. I've never heard anyone refer to a tag cloud as being based on how often a term is searched for -- everyone i know uses the frequency of words in the corpus, sometimes with a decay function to promote words mentioned in more recent docs. Solr doesn't keep any record of the searches performed, so to build a tag cloud based on query popularity you would need to mine your logs. if you want a tag cloud based on the frequency of words in your corpus, the faceting approach mentioned would work -- but a simpler way to get term counts for the whole index (*:*) would be the TermsComponent. you only really need the facet based solution if you want a cloud based on a subset of documents, (ie: a cloud for all documents matching category:computer) -Hoss
