Rather than directly searching with the Query returned by QueryParser you can
combine that Query with other Queries using the BooleanQuery class, then call
search using the composite BooleanQuery. For example:
BooleanQuery bq = new BooleanQuery();
bq.Add( Lucene.Net.QueryParsers.QueryParser.Parse( criteria, "_contents", new
StandardAnalyzer() ), BooleanClause.Occur.SHOULD);
bq.Add( new TermQuery(new Term("filetype","txt")),
BooleanClause.Occur.MUST_NOT);
hits = indexSearcher.Search(bq);
In this case I am searching for both information in the field "_contents" and
for information in a field "filetype".

Subject: Searching Multiple Fields
Hi, I have the following code that is working:
Public Function SearchCities(ByVal SearchQuery As String) As
Lucene.Net.Search.Hits
Dim Analyzer As New Lucene.Net.Analysis.WhitespaceAnalyzer()
Dim QueryParser As New
Lucene.Net.QueryParsers.QueryParser("contents", Analyzer)
Dim Query As Lucene.Net.Search.Query = QueryParser.Parse(SearchQuery)
Return _CitySearcher.Search(Query)
End Function
It is searching the "contents" field. Is it possible to have it
search more than one field at the same time without having to run two
different searches. If I do have to run the searches separate, is
there a way to "merge" the results?
Thanks!
Micky
