Hi Folks,
I have an issue which I hope someone can help me with.
I've developed a custom analyzer which is working perfectly well during
indexing, formats dates & numbers and everything else just as we require for
proficient indexing.
When searching it works fine for single fields, but if i need to search on a
Range the custom parser is not invoked to format the field correctly and I'm
wondering if anyone has any idea why or what i need to do to correct the
problem.
For example, the following works perfectly
var queryRunner = new lugen.lib.QueryRunner("DATE_CREATED:27-May-2009");
but this does not, the custom parser which format dates/numbers etc
correctly does not get invoked.
var queryRunner = new lugen.lib.QueryRunner("DATE_CREATED:[1-Jan-2008 TO
31-DEC-2010]");
Anyone any ideas what could be happening, or an approach I should take to
get it working, I'm sure I'm doing something wrong as this must be a
requirement for many people.
Kind Regards
Noel Lysaght
I include the QueryRunner class for completeness. It just invokes a
QueryParser at the moment, everything is in the constructor while testing
so please forgive me that.
public class QueryRunner
{
const string INDEX_FILE = "c:\\temp\\lucene\\lugen.index";
string _queryString = null;
public QueryRunner(string queryString)
{
_queryString = queryString;
var dir = Lucene.Net.Store.FSDirectory.GetDirectory(INDEX_FILE, false);
var reader = Lucene.Net.Index.IndexReader.Open(dir);
var searcher = new Lucene.Net.Search.IndexSearcher(reader);
Lucene.Net.QueryParsers.QueryParser parser = new
Lucene.Net.QueryParsers.QueryParser("defaultField", new
CustomFieldAnalyzer());
var query = parser.Parse(_queryString);
var hits = searcher.Search(query);
}
}
