Re: Query syntax on Keyword field question

[Erik Hatcher]

QueryParser and Field.Keyword fields are a strange mix.  For some 
background, check the archives as this has been covered pretty 
extensively.

A quick answer is yes you can use MFQP and QP with keyword fields, 
however you need to be careful which analyzer you use.  
PerFieldAnalyzerWrapper is a good solution - you'll just need to use an 
analyzer for your keyword field which simply tokenizes the whole string 
as one chunk.  Perhaps such an analyzer should be made part of the 
core?

I have since learned that using the TermQuery instead of the 
MultiFieldQueryParser works for the keyword field in question below 
(HW-NCI_TOPICS).

apiQuery = new BooleanQuery();
apiQuery.add(new TermQuery(new Term("category", "HW-NCI_TOPICS")), 
true, false);

This finds a match.

I found a message that talked about having to use the the Query API 
when searching Keyword fields in the index.  Is this true?

Is there not a way to get the MultiFieldQueryParser to find a match on 
this keyword?

thanks,
chad.

        Hello,
        
        How can I format a query to get a hit?
        
        I'm using the StandardAnalyzer() at both index and search time.
        
        If I'm indexing a field like this:
        
        luceneDocument.add(Field.Keyword("category","HW-NCI_TOPICS"));
        
        I've tried the following with no success:
        
        //      String searchArgs = "HW\\-NCI_TOPICS";
        //      String searchArgs = "HW\\-NCI_TOPICS".toLowerCase();
        //      String searchArgs = "+HW+NCI+TOPICS";
              //this works with .Text field
        //      String searchArgs = "+hw+nci+topics";
        //      String searchArgs = "hw nci topics";
        
        thanks,
        chad.
