What we did in DBSight is to provide a reserved list of words for every
Lucene Analyzer.
This way you can handle any special characters like C++ and C#.
Any common analyzers usually are not suitable for these special words.

Instant Scalable Full-Text Search
The index *should* grow after merging/optimizing, but it will only do this,
if the fields you had compressed were not bigger then without compression.
One of the tests showed: A string field with 80 ascii chars needed
compressed about 250 bytes, which is 3 times (as chars are UTF-8 encoded)
the unc
Hi Tom,
Pt 3: As per my knowledge, it wouldn't be a 'mixture' of 2 index types.
Rather, as soon as you optimize (or do a IndexWriter operation on the
current index), it would expand the index to a non compressed format. I read
it somewhere in the release notes that on doing so, a growth in the inde

I'm upgrading from 2.3.1 to 3.0.0. I have 3.0.0 index readers ready to go
into production and writers in the process of upgrading to 3.0.0.
I think understand the implications of

Hi Michael,
I am reporting my experience with the codec interface. I have
successfully implemented my own encoding, which is a kind of simplified
tree-based encoding (similarly to what you can find in XML IR). You can

Hi
Sounds very odd. I suggest you break it down into the smallest
self-contained program/test case that demonstrates the problem. If
that doesn't help you find the problem, post it here.

How long does Lucene take to build the ords for the toplevel reader?
You should be able to just time FieldCache.getStringIndex(topLevelReader).
I think your 8.5 seconds for first Lucene search was with the
StringIndex computed per segment?

I've spend the last day working on a multipass order builder, where the
order is defined by a Collator and stored in an int-array. Compromising
a bit on the "minimal memory at all cost"-approach resulted in a fair
boost in speed, but it's still very slow for the first sorted search,
compared to Luc
MappingCharFilter can be used to convert c++ to cplusplus.

By the way the same search + filter combination but with a sort on another
field (string) works. It seems only the float sort isn't working. The float
sort is working correctly in other conditions though.
I'm very puzzled !
