I use a sphinx as fulltext search engine, and ranker option is set to proximity.
How can I set as ranker this formula: proximity + count of words in somecolumn / hit_count?
I don't know, how can I get words count.
I've tried to add a column with count of words into the index, but somecolumn is a huge concate field, and I can't use this example, because it will be too slow query.
