wildcard support
Hi
I am using the highlightertest.java to extract the wild card terms.
I use the queryParser to parse my queryString
Then i store the text in a RAM directory ( which i want to scan)
and then rewrite it as mentioned in the highlighter example
query=query.rewrite(reader)
Now if i print the query, i see that it does not contain anything
I repeat the query does not contain anything
What is the reason for this problem? Any help would be appreciated.

Hi,
Yes, no IOException means all went well, I believe.

Hi,
all I want to know about IndexWriter.addIndexes() is if there is a way to
tell if merging was successful or not. Or can I be sure that if no
IOException is thrown, everything is fine and I can delete the old indexes?
Regards
Frank

If you've rewritten a WildcardQuery and get an empty query, that
means that no terms matched the wildcard expression in the index
pointed to by the IndexReader you provided.
