Somewhere in the list, I remember one of the guys who know what
they're talking about mentions something about KeywordAnalyzer
being "subject to the meta-semantics of the QueryParser".
So try looking at query.toString() in your example. What I think you'll
find is that KeywordAnalyzer doesn't quite do what you expect at
query time. This code
QueryParser qp = new QueryParser("field", new
KeywordAnalyzer());
Query q = qp.parse("Does this tokenize*");
System.out.println(q.toString());
Produces
field:Does field:this field:tokenize*
which isn't really what you're looking for, I don't think. In fact, I don't
see any difference between this and WhitespaceAnalyzer. What I
think you want is
Try rewriting the query and dumping the output to see how your
term expands...
If you haven't already, get a copy of Luke (google Lucene Luke). That'll
allow you to examine how different analyzers work at query time and
give you a much better idea of what is going on.....
But it's a beautiful Saturday, and I'm going to go outside and garden so....

I seem to be having problems using a * in a phrase term query
This is my search String, its not finding any matches
54:"MusicIP PUID*"
If I match on a particular record it works ok
54:"MusicIP PUIDa39494bf-927e-1638-fb06-782ec55ac22d"
The problem appears to be the space character, because I have another
situation where there is no space and it works ok.
I use a keyword analyser to create the index so the value 'MusicIP
PUIDa39494bf-927e-1638-fb06-782ec55ac22d' is stored
as a single value, and then use the same analyser in my search code,
which is as follows:
public List <Integer> generalSearch(String luceneSearch)
{
System.out.println("Search Query Is"+luceneSearch);
List <Integer> matchingRows = new ArrayList<Integer>();
try
{
IndexSearcher is = new IndexSearcher(directory);
//Build a query based on the searchString and cached analyzer
QueryParser parser = new QueryParser(ROW_NUMBER,analyzer);
Query query = parser.parse(luceneSearch);
//run the search
Hits hits = is.search(query);
Iterator i = hits.iterator();
while(i.hasNext())
{
Document doc = ((Hit)i.next()).getDocument();
matchingRows.add(new
Integer(doc.getField(ROW_NUMBER).stringValue()));
}
}
catch (Exception e)
{
e.printStackTrace();
}
return matchingRows;
}
I cant see what the problem is, thanks paul
