Hi,
I have a few questions regarding more like this:
1. In MoreLikeThis, it seems like the check for fieldNames being null and
fetching them from the reader is not done for all the like methods. For
example, it does not look like it is done at all for like(Reader r), and on
the other hand
you please use the Lucene code format? (Eclipse/IntelliJ
templates are at the bottom of
http://wiki.apache.org/lucene-java/HowToContribute )

a lot of searches.
I need to spend a little more time looking at it before I understand it in more
detail.
Before then - have you tested this on a big (millions of docs/terms) index?
Some performance figures would be useful to accompany this.

Mark

Hi,
I would like to contribute a class based on the MoreLikeThis class in
contrib/queries that generates a query based on the tags associated
with a document. The class assumes that documents are tagged with a
set of tags (which are stored in the index in a seperate Field). The
class determines
is in the
IndexReader, but suspect that would be a can of worms. Comments?

I'm confused: how come you are not already seeing the benefits of this
cache? You ought to see MLT queries going faster. This core cache was first
added in 2.4.x; it looks like you were testing against 2.4.1 (from the Affects
Version on this issue).

Good question...
Good answer. Thanks.
I guess the next step then is to understand why the TermInfo cache
isn't getting the performance to where it could be. It'll take me a
while to get to the point where I can answer that question. If
that is not MLT related.
A lot of MLTs use the same terms, and I have a good size cache for it, meaning
most terms I use in MLT can be retrieved from there. Seeing as MLT in my
circumstance is one of the slower bits, this can give me a good advantage.

Plus, the original motivation for this (LUCENE-1195) was because
queries in general look up the same term at least 2 times during their

This will be fixed as part of LUCENE-1460.
MoreLikeThis should use

should be an LRU cache with a settable maximum number of entries to stop it
growing forever if you do a lot of like this queries on large indexes with many
unique terms.
Otherwise nice addition, has sped up my more like this queries a bit.

Carl, do you have any data on how this has changed performance in your system?
My use case is a limited vocabulary so the performance gain was large.

Lucene is completely new to me. I just downloaded 1.9.1 and started

Where can I find it?
