Hello everybody,
I need to index and search real numbers in Lucene. I found NumberUtils class
in Solr project which permits one to encode doubles into string so that
alpha numeric ordering would correctly correspond to the ordering on
numbers. When I use ConstantScoreRangeQuery programmatically everything
works just fine. However when I convert this query to a string, parse it
with QueryParser and use the resulting query – no result are found.
ConstantScoreRangeQuery wquery =
new ConstantScoreRangeQuery("westbc", null,
NumberUtils.double2sortableStr(-110.500000), false, true);
Hits hits = is.search(wquery); //returns expected results
Now if I do
String wqueryString = wquery.toString();
QueryParser queryParser = new QueryParser("westbc", new KeywordAnalyzer());
Query query = queryParser.parse(wqueryString);
Hits hits = is.search(query); // returns nothing
Interesting is that System.out.println(wquery.toString()) looks exactly the
same as System.out.println(query.toString()).
Any ideas welcome.
Thanks,
Leon
