Hi Che-
The presort method was our first approach but this doesn't work
in practice because we update the index incrementally and insertion order
doesn't match date ordering as we add updates.
I don't think sorting top hits only will deliver what the user is
expecting -- that is, results

Hi Erik,
Thanks for the reply. All dateTime fields are zero-padded and the
same length, and each indexed document has a valid dateTime value.
Regarding the sort type, INT generates a ParseException, I assume
because the string has too many digits to fit in an int. I looked
for a LONG type but
Just like Google said: full text search service is not traditional
database application. Lucene is not a database too: if you wanna sort on
some fields, you'd better pre-sort it before it indexed: like date. then
get results by doc id.
For lucene you can only sort results in top hits. if you so
Hi all:
did you tried to increase IndexWriter.mergeFactor. I tried to increase
it to 1000 and index speed is about 10 time faster than defualt = 10 .

Thanks Pierrick.
Are you say that I should construct Token in analyzer like
new Token ("chem_H2O", 100, 103, "chem");
note that chem_ is added prefix to H2O, and 100 to 103 is length of H2O rather
than chem_H2O?
I also have some further problem and not sure if can be solved by this approch.

Hi,
Thanks for your suggestion. I haven't yet tried your
technique but I did try something similar by tweaking
some Indexwriter properties like mergeFactor and
minMergeDocs and it did certainly speed up the process
a lot. I am sure the same can be achieved with what
you suggest because it is essen

Hi,
Thanks for your reply.
One more question. You mentioned that your technique
can be used for wildcard search like ex. *123* . But
say I only need something like 123* i.e. wildcard only
at the end and NOT on both sides, then how can one use
your technique to avoid TooManyClauseException?
Thanks

Well, LuceneRAR isn't transactional - yet. As soon as I figure out how to
queue deletes, though... :)

I am thinking maybe use a message queue that feeds an indexing

Hi ALL,
We have built Lucene indexes on a Solaris box. We have tested them and they
can be accessed OK when residing on a native Linux filesystem.
What we like to do is export through NFS the Lucene indexes from the
Solaris box to the Linux box (mainly for development and testing purposes).

On some systems I have seen big speed increases by indexing to a
RAMDirectory and periodically "merging" into an on disk directory
every X number of docs. May or may not help in this case. In the
first case a used this, it took indexing down from a few hours to 30
minutes for a few million docume

Hi guys,
If a field is indexed as UnStored how can I get it value?
I tried document.get("UnStored_field") it returns null.
You didn't store it, so it's not there. If the field happens to be a
single Term, you might be able to find it
