: Currently, lucene query syntax supports range query like foo:[a TO b]. I
: didn't find a way to support one boundary range. (Or did I miss something?)
FWIW: the SolrQueryParser (which subclasses the Lucene QueryParser)
accomplishes this by treating '*' as special values.
users that want similar behavior with Lucene should be able to get it
fairly trivially with something like...
QueryParser qp = new QueryParser("foo", analyzer) {
protected Query newRangeQuery(String f, String a, String b, boolean i) {
return super.newRangeQuery(f, "*".equals(a) ? null : a,
"*".equals(b) ? null : b, i);
}
}
but commiting a chacne like that to the existing Lucene QueryParser might
break things for some people (although it seems unlikely)
