I also noticed that you have "MUST" for your full string of fuzzy terms -
that means everyone of them must appear in an indexed document to be
matched. Is it possible that maybe even one term was not in the same indexed
document?
Try to provide a complete example that shows the input data and the query -
all the literals. In other words, construct a minimal test case that shows
the failure.

Hi Jack,
ed is set to 1 here and I have lowercased all the data and queries.
Regarding the indexed data factor you mentioned, can you elaborate more?
Thanks!
George

That depends on the value of "ed", and the indexed data.
Another factor to take into consideration is that a case change ("Star"
vs. "star") also counts as an edit.

Hi Jack,
Thanks for your reply!
I don't think I passed the prefixLength parameter in.
Here is the code I used to build the FuzzyQuery:
String[] words = str.split("\\+");
BooleanQuery query = new BooleanQuery();
for (int i=0; i<words.length; i++)
{
Term t = new Term(field, words[i]);
FuzzyQuery fq = new FuzzyQuery(t, ed);
query.add(fq, BooleanClause.Occur.MUST);
}
int k = 10;
TopDocs results = searcher.search(query, k);
Does it look right to you?
Thanks!
George
