It's not clear to me how to query non text fields, ex an int field.
Could you make an example or a test about it?

Hi, the default lucene query parser doesn't handle numeric fields, unfortunately, mainly because lucene is schemaless and it's not possible to detect old-style numeric fields just from index data.

You can override QueryParser#newTermQuery() and QueryParser#newRangeQuery() to correctly deal with old-style numerics or new-style points, depending on your own schema information - the solr and elasticsearch query parsers do this, and they're a good place to look for examples.
