it, and how to do it. This leaves the tricky issue of mapping
from a specific database to a specific lucene index up to the
developer.

It sounds like you ought to at least seriously consider using
Lucene, if you can find or implement equivalent features, or decide
you can live without them.

specifics to give you a warm and fuzzy feeling.
Lucene isn't perfect for _everything_ (and anybody who claims that a
given technology *is* perfect for _everything_ is lying). But it's
quite good for a number of things.

Hey folks,
They've put an apache wiki at nagoya. I took the liberty of
writing a paragraph about Lucene, please feel free to completely
revise it :-).

Take it all with a grain of salt
machine). But they might
be interested in a way to offer it as an optional feature, where
people using lucene in a constrained environment could configure
lucene to be careful about how many files it keeps open at any given
time.

should look at Xindice (http://xml.apache.org/xindice/)
which is an XML database. You might find it easier to adapt that to your
needs. I'm kind of curious as to how fast Xindice's XPath execution is, and
what their indexing is based on - there might be a use for Lucene there.

If you could either include me in the CC list, or send me a

discussion here, I'd appreciate it.

A more realistic implementation would use an exclude file of
filenames to ignore, load them into a collection (probably a HashSet)
and keep that collection around as an instance variable. Then
checkFileName() just returns !excludedSet.contains(name).

solaris machines the default ulimit used to be 24 - that's 24 open

assume it's actually a memory problem, particularly if a memory
