I have code as part of LUCENE-5318 that counts terms that cooccur within a window of where your query terms appear. This makes a really useful query term recommender, and the math is dirt simple.
INPUT Doc1: quick brown fox jumps over the lazy dog Doc2: quick green fox leaps over the lazy dog Query: fox , window size before =2, window size after = 3 OUTPUT: Quick: 2 (and 2 * idf(quick)) Over: 2 Brown: 1 Green: 1 Jumps: 1 Leaps: 1 The query can be anything that can be transformed into a SpanQuery. If you want examples or help, just drop a line.
