It comes down to your choice of analyzer.
Don't forget your "all" field is broken down into
discreet terms by your choice of analyzer.
Most often, you will want to use the same analyzer at
query-time with the query parser to make sure the
user's input matches the stored document terms.
If you get it wrong (say using an analyzer that
doesn't lower-case) you'll find nothing:
Kylie != kylie
If you aren't using a query parser and manually
constructing FuzzyQuery objects programmatically the
same logic applies (psueodocode): new FuzzyQuery(new Term("Kylie"))
!= "kylie"
Thanks for the help. I'm using the StandardAnalyzer to do the indexing
(which lower cases everything) and I'm lowercasing my search string
before I build the Term. So shouldn't be an issue, are there other
factors in this vein that may cause problems considering that this is
an alphabetic string which shouldn't be in any stop word lists.
Indexed as "kylie minogue: kyliefever2002 (live in manchester)"
Searched with "klyie"
Using new FuzzyQuery( new Term("klyie", 0.5f, 1) );
No matches! I don't get it :(
I've even gone as far as to run the search term through the
StandardAnalyzer, grab the tokens and rebuild the search string (even
though it's only one, valid token). I'm clutching at straws now but
could it be that I build a BooleanQuery (OR) even if there is only one
search term? In this case it's basically like this
BooleanQuery query = new BooleanQuery();
query.add( new FuzzyQuery( new Term( "all", "klyie"), 0.5f, 1, false,
false);
Hits hits = is.search(query);
