These methods look promising in terms of ease of use of FunctionscoreQuery but they dont exist in Lucene 6.6.0. static FunctionScoreQueryboostByQuery(Query in, Query boostMatch, float boostValue) Returns a FunctionScoreQuery where the scores of a wrapped query are multiplied by a boost fac

Re: Search in lines, so need to index lines?

It sounds as if you must integrate a regex search into an existing framework. You have good ammunition here for explaining why this may not be a good idea since the performance will not be good.
