Hi,
I have a big index, and when I searched it with a title string "Cla$$War",
Lucene became very slow. It doesn't happen when I searched with other title
string such as "Gone with Wind". Does the "$$" affect the search performance?
Thanks,
Cheng

Sounds extremely unlikely. What is the query? What analyzer? What
version of lucene? What about other strings containing $$?

I'm surprised that you got no hits with autoGeneratePhraseQueries - which
suggests that maybe the index didn't use the same analyzer or maybe the
literal text in the title is not exactly what you think it is.
You could use the WhitespaceAnalyzer, but that would leav

What file handlers did you guy refer to?
I opened the index directory only. Is this the file handler? Also, how to
safely and effectively close the index directory?
I found the link's explanation somewhat self-contradictory. After I read it, I
am confused if I should close the file handlers

Mike, thanks for reply.
Can you please elaborate a little bit more on " If you don't need norms
(don't boost, lengths don't vary much or you
don't care to have field length impact scoring) you can omit norms"?
When do you expect the handling of nested document will be applicable?

be released until the next release
(though you can use it on the trunk/3.x tip as well, once it's
committed).

Hi,
Quite a few Lucene examples on lines shows how to insert multiple fields
into a Document and how to query the indexed file with certain fields and
queried text. I would like to know:
1. How to do a cross-field search?
2. How to specify some key fields as well as some less i
I read the lucene in action book and just tested the
FSversusRAMDirectoryTest.java with the following uncommented:
///**
//// change to adjust performance of indexing with FSDirectory
writer.mergeFactor = 100;
writer.maxMergeDocs = 99;
writer.minM
RAMDir would be slower... FSDir still must go

I just saw this:
https://issues.apache.org/jira/secure/attachment/12480123/LUCENE-2454.patch
One comment: should Lucene provide nested doc indexing as well?
Would love to see it’s available.
