I was wondering if there is a "search based" method to find the top-k frequent phrases in a set of documents.( I do not have a particular phrase in mind so PhraseQuery can probably be ruled out). I have implemented something that works using termvectors and termpositions but the performance is not great so far since I am basically iterating multiple times and hacking my way around. I was wondering if an API exists for finding frequent phrases and/or if someone could point me to some code for the same.
Thanks.
