Re: Quest about Lucene's IndexSearcher.search(Query query, int n) API's parameter n

You can sort with custom formulas. All values that are needed for calculation must be part of the index as docvalues fields. You can then use expressions module to supply a formula for the calculation, which may include the original score. The expressions module can override the score (so standa

Quest about Lucene's IndexSearcher.search(Query query, int n) API's parameter n

I'm doing a POI(Point-of-interest) search using lucene, each POI has a "location" which is a GeoPoint/LonLat type. I need do a keyword-range search but the query result POIs need to sort by distance to a starting point. This "distance", in fact, is a dynamic computed property which cannot be used

How to query for 'any word' in a phrase

Dear all, Is there a way to construct (spans?) a phrase search like the following: the quick brown * jumps over the * * where * = any word but exactly 1 word I introduced these *’s at a specific position, so a PhraseQuery with slop of 2 is just not good enough and the two *’s at the end must be
