Yes, I'm sure. I debug the code, and look at the files in the index folder,
it has a write.lock file before this line of code:
if (!(IndexWriter.isLock(NIOFSDirectory.open("fileAddr"{
//do something
}
and after passing this line, index folder does not contain write.lock file
and code goes to
what's your analyzer?
if you use standard analyzer, I think this won't happen.
if you want to get exact match of name field, you should index this
field but not analyze it.

Hi
I am using lucene for search implementation .
I have created index with two columns
(1) Name
(2) Year
I stored values like
AC 2001
AC 2002
ACC 2004
ACC 2001
ACJ 2006
ACJ 2007
I want to query in index to get year of AC ..When i query with Name:AC or
Name: "AC" , it gives me all record with
Hmm - I looked at Spans more carefully, and it appears as if your idea
about a "fake" Query (some kind of SpanAllQuery would be called for)
would work well, and would probably be much simpler to implement. It
wouldn't preclude the kind of optimization I was talking about either,
but I don't kn
I think what I have in mind would be purely an artifact of the parser; a
term that would always be optimized away, either vanishing or gobbling
up the whole query. So if you had n(A,*), you would just get "A". If
you had and(A, not(*)) (is that the surround syntax for not?) you would
get not

You need to have relevance judgements (qrels), so that benchmark knows
which documents are relevant to which query.

Look at IndexReader.docFreq

Hi Mike: wheres for the normal queryparser this Query doesn't consult
the positions file and is trivial, how would such a query be
implemented for the surround parser? As a single span that matches all
positions for the whole document? Maybe it could be a "fake span" for
each document of 0 ... Inte
No, that doesn't work either - it works for the lucene query parser, but
not for the *surround* query parser, which I'm using because it has a
syntax for span queries.

but those don't parse. I looked at the grammar and I don't think there

I need to know if there is any way to calculate precision and recall of the
system with your own documents corpora and list of queries using lucene
benchmark package or any other way.

Hmm, not good. Are you sure the index was previously locked?
Can you describe your environment? Which OS / Directory class are you using?
Maybe boil down to a small code fragment showing the issue?

I want to ask about the lucene.benchmark which I used it to mauser the
precision and recall in my lucene code .
basically I used this code
File topicsFile = new File("C:\\test\\topicfile.txt");
File qrelsFile = new File("C:\\test\\qrles.txt");
try (Directory dir = FSDirectory.o
Hi all
While I am using IndexWriter.isLock(), this method unlocks the index and
returns false.
Can anyone tell me why?
