How to search term in a certain range in Lucene

Question

I want to search terms which is in [0, 10], and terms are from the field "CityId" that is stored as Integer. What I have written is below:

String queryStr = "CityId : [0, 10]";
Query query = parser.parse(queryStr);
TopDocs topDocs = searcher.search(queryStr);

And what is the reult of your querry? If you dont want to parse a querry string you can build a NumericRangeQuery like this: NumericRangeQuery. newIntRange(0,10,true, true) — TobiSH, Apr 09 '16 at 15:38

The standard QueryParser does not support numeric ranges. The range queries supported by the QueryParser are Lexicographic, rather than numeric. You will need to use a NumericRangeQuery for this:

Query query = NumericRangeQuery.newIntRange("CityId", 0, 10, true, true);

Also, might be good to refer to the QueryParser documentation for what Lucene's query syntax looks like. Range queries upper and lower bounds are not separated by a comma. It should look like myField:[begin TO end] (again, though, this will not be a numeric range).
