Same as the known length example, but insert the length into regex: int length = 5; String[] parts = str.split("(?<=\\G.{" + length + "})");

A query can be boosted to increase it's score relative to other subqueries. This is done by wrapping it with a BoostQuery Query lessRelevantQuery = new TermQuery(new Term("fieldname", "ipsum")); //Five times as interesting Query highlyRelevantQuery = new BoostQuery( ...
