Lucene was then chosen as a top-level Apache Software Foundation project name. It’s the original Java indexing and search library created by Doug Cutting. The question is a follow up to this question that pointed out the problem, but not the reason: Lucene LongPoint Range search doesn't work
Is this a bug in query parser or do I miss an important point, like QueryParser takes the lexical and not numerical value? How can I chance this without using the query API but parsing the string? On the other hand, via API it works (But I give up the convenient way to just use the query as input): Query query = LongPoint.newRangeQuery("value", 100L, 202L) // Returns 1, 2 and 3 Query query = parser.parse("id:1 OR value:167") // Returns only document with ID 1 and not 1 Query query = parser.parse("id:1 OR id:3") īut this does not work for range queries like these one: Query query = parser.parse("value:") // Returns nothing I parse these queries via QueryParser parser = new QueryParser("", indexWriter.getAnalyzer()) One thing I really like about Lucene is the query language where I/an application user) can write dynamic queries.
