Hi,
FuzzyQuery (in the 2.2.0 API) may take 3 arguments,
term , minimumSimilarity and prefixLength
Is there any syntax to specify the 3rd argument
in a query term for QueryParser?
(I haven't found any the current docs)
Many thanks for a hint,

Hi,
according to the LiA book the FuzzyQuery distance is computed as
1- distance / min(textlen,targetlen)

Field.Store.YES, Field.Index.TOKENIZED))

Hi,
please help I am totally puzzled.
The same query, once with a direct call to FuzzyQuery
succeeds while the same query with QueryParser fails.
What am I missing?
Sorry, I'm using pylucene (with lucene-java-2.2.0-603782)
#!/usr/bin/python
import lucene
from lucene import *
So does it mean that if I my query doesn't support prefix or wild-char
queries then I don't need to use rewrite() for highlighting?

See in Lucene FAQ:
Are Wildcard, Prefix, and Fuzzy queries case sensitive?

As long as the terms you want highlighted are extractable from the
Query instance, all is fine.
However, it

I have the following code for search:
BooleanQuery bQuery = new BooleanQuery();
Query queryAuthor;
queryAuthor = new TermQuery(new Term(IFIELD_LEAD_AUTHOR,
author.trim().toLowerCase()));
bQuery.add(queryAuthor, BooleanClause.Occur.MUST);
Hi,
Do you mean that your query phrase is Health Safety,
but docs with Health and Safety returned?
If that is the case, the reason is that StandardAnalyzer
filters out and (also or, in and others) as stop
words during indexing, and the QueryParser filters those
words out also.
Best regards,

Either index them as a series of tokens:
org
org.apache
org.apache.lucene
org.apache.lucene.document
org.apache.lucene.document.Document
or index them as a single token, and use prefix queries (this is what
I do for reverse domain names):
classname:(org.apache org.apache.*)
Note that
