not?

Hi Lucene list,
We have the need for analysed and 'not analysed/not tokenised' clauses
within one query. Imagine an unparsed query like:
+title:Hello World +path:Resources\Live\1
In the above example we would want the first clause

Everything is relative.

If your query isn't entered by users, you shouldn't use query parser in
most cases anyway.
I'd go even further and say in all cases.
If you use lucene as a search server you have to provide the query somehow.
E.g. we have an php application, that sends queries to a
Hi,
(First of all : what is the plurial of index in english ; indexes or indices

I want to search into several indexes (indices ?).
For that, I parse a new query using QueryParser or MultiFieldQueryParser.
Then I search my indexes using the MultiSearcher class.
Ok, but the
PDF(s) can definitely slow things down, depending on their size.
If there are a few larger PDF documents that time is definitely possible.

As I understand it optimization is when you merge several segments into one
allowing for faster queries.
The FAQs and API have further details.

We used indexes in Lucene in Action. Its a bit ambiguous in English,
but indexes sounds less formal and is acceptable.

This feature doesn't exist as such.
You could search for it and if results come up, then the word is in the
documents it returns.

If you are going to compare scores across multiple indices, I'd suggest

I did following test:
I created the RAM folder on my Red Hat box and copied c. 1Gb of indexes
there.
I expected the queries to run much quicker.
In reality it was even sometimes slower(sic!)
Lucene has it's own RAM disk functionality. If I implement it, would it
bring any benefits?

Hello again,
I've modified DateFilter to filter out document IDs as suggested. All seems to
be running well until I tried a specific test case. All my documents have IDs
in the 400,000 range. If I set my lower limit to 5, nothing comes back. After
examining the code, I found the issue to be at
It sounds like you need to pad your numbers with leading zeroes, i.e.
use the same type of encoding as is required by RangeQuery's. If you
query with 05 instead of 5 do you get what you expect? If all your
document id's are fixed length, then string comparison will be
isomorphic to integer
Is there a way to auto-generate uid in Lucene? Even it is just a way to
query the highest uid and let the application add one to it will do.
Thanks.

Hi folks:
Is there an indexing benchmark somewhere? I see a search
benchmark on the lucene home site.

What would the purpose of an auto-generated UID be?
But no, Lucene does not generate UID's for you. Documents are numbered
internally by their insertion order. This number changes, however,
when documents are deleted in the middle and the index is optimized.

If you are on linux the number of file handles for a session is much lower than
that for the whole machine. ulimit -n will tell you. There are instructions
on the web for changing this setting, it involves the /etc/security/limits.conf
and setting the values for nofile.

Click the here link on the Lucene home page.
We Lucene committers have been very very lame and have not published
the binary distribution appropriately for the mirrors to pick up. One
of these days we'll correct this, but for now you can click the link
from the announcement on the home page.
Just to clarify. I have a Field 'uid' those value is an unique integer. I
use it as a key to the document stored externally. I don't mean Lucene's
internal document number.
I was wonder if there is a method to query the highest value of a field,
perhaps something like:

Not exactly sure what you're trying to do. You can easily generate a number
when you index each Document and insert it in a uid field (which is, BTW, what
I do), and if you base it on a timestamp plus some characteristic of the
document (which is also what I do), it should always be unique.
I'm sorry, I wasn't involved in the original conversation but maybe I
can jump in with some info that will help.
The number of files depends on the merge factor, number of segments, and
number of indexed fields in your index. It also depends on whether you
are using compound files or not (this

Is it possible to combine Lucene and multi-dimensional scaling in some way?
