Solr statistical information

Is that possible to get some kind of stats from solr. E.g. Most f开发者_C百科requently used words (unigrams), or phrases (bi- trigrams)?

Take a look at the schema browser (e.g. http://localhost:8983/solr/admin/schema.jsp), it gives you the top terms for any given field. You can also access this information with the LukeRequestHandler (e.g. http://localhost:8983/solr/admin/luke).

The TermsComponent also gives you information about indexed terms in a field and the number of documents that match each term.

The StatsComponent gives you statististics about numeric fields.
