Hi all
I searched through the mail-list archives and saw that sometime ago Toby
Cole was going to integrate a spellchecker named Spelt into Solr. Does
anyone now what's the status of this? Anyone tried to use it with Solr? Does
it make sense to try it instead of standard spell checker?

Hi Raghu
Let me describe our use case in more details. Probably that will clarify
things.
The usual use case for Lucene/Solr is retrieving of small portion of the
result set (10-20 documents). In our case we need to read the whole result
set and this creates huge load on Lucene index, meaning a
For example, if we get query tommyhitfiger and have terms tommy and
hitfiger in the index, how to fix the query?
The usual approach to solving this is to index compound words, i.e. when
producing a spellchecker dictionary add a record tommyhitfiger with a
field that points to tommy
Hi
If a user issued a misspelled query, forgetting to place space between
words, is it possible to fix it with a spell checker or by some other
mechanism?
For example, if we get query tommyhitfiger and have terms tommy and
hitfiger in the index, how to fix the query?

Hi all!
Is there any ready-for-use filter which performs acronyms normalization such
as I.N.C.-INC?
I see that Lucene's StandardFilter can do this but we can't use it as we're
using WhitespaceTokenizer instead of StandardTokenizer.

Hi
We obtain ALL documents for every query, the index size is about 50k. We use
number of stored fields. Often the result set size is several thousands of
docs.
We performed the following things to make it faster:
1. Use EmbeddedSolrServer
2. Patch Solr to avoid unnecessary marshalling while

Tom,
AFAIK Lucene performance is very much dependent on file system cache size,
in case of large index. So if you see lots of IO, this probably means that
your system doesn't have enough memory to hold large file system cache,
suitable for your index size. In this case you don't need to give more

But it's what lucene index locking is for, isn't it? Locking should handle
that issue. Solr doesn't use index locking in a proper way?

My most recent example of this is BooleanQuery's performance. It
turns out, if you setAllowDocsOutOfOrder(true), it yields a sizable
performance gain (27% on my most recent test) for OR queries.
Mike,
Can you please point me to some information concerning allowDocsOutOfOrder?

Hi,
I know that when starting Solr checks index directory existence, and creates
new fresh index if it doesn't exist. Does it help? If no, the next step I'd
do in your case is patching SolrCore.initIndex method - insert some logging,
or run EmbeddedSolrServer with debugger etc.

Hi!
I agree that Solr is difficult to extend in many cases. We just patch Solr,
and I guess many other users patch it too. What I propose is to create some
Solr-community site (Solr incubator?) to public patches there, and Solr core
team could then look there and choose patches to apply to the

Base on docs in the wiki I thought that the following query should return

But in fact it finds all the products in the index and it seems that
socks products have higher score

You should probably just look at the index version number to figure out if
the name changed. If you are looking at segments.gen, you are looking at a

Our index could be much smaller if we could store some of fields not in

All I've found until now is ExternalFileField class which shows that it's

Hi all
We want to use Solr with lucene Directory implementation which places index
into Coherence data grid.
I fact I managed to run Solr in such configuration although I had to patch
it.
I think that the issue about alternate directories support (SOLR-465) should
be re-opened because there are
