BTW, Have you changed the MergePolicy & MergeScheduler settings also? Since
Lucene 3.x/3.5 onwards,
there have been new MergePolicy & MergeScheduler implementations available,
like TieredMergePolicy & ConcurrentMergeScheduler.

If you are not searching for the specific digit and want to match all
documents that start with any digit, you could as part of the indexing
process, have another field say startsWithDigit and set it to true if
it the title begins with a digit. All you need to do at query time then
is query for sta
We are upgrading our search infrastructure from Lucene 2.3.1 to Lucene 3.5.
I am in the process of load testing and I could find that Lucene 2.3.1
could index 32,000 docs per second, whereas Lucene 3.5 could index only
around 17,000 docs per second.

Thanks all, for your inputs.
We found what the problem was, the reason certain entries were missing from
the index and not from the MySQL search results was that we had some
customized transformers in the data config, that skipped the entries when a
particular field was missing.

Hmmm... how could I have gotten so confused?!?! Actually, I recognized my
mistake yesterday (after reading the code some more for David's Jira) but
hadn't gotten around to correcting myself.
In any case, the original problematic scenario may have been simply copying

See "Function Query":

If you are using the dismax or edismax query parser you can use the "bf"
request parameter.

If you download version 3.6 of solr there's a directory dist/solrj-lib

Here's a quick thing to check. Delete your index and do a fresh import. Then
go to the admin/statistics. Check the "numDocs" and "maxDocs" entries. If
they're different, it means that some of your documents have been deleted.

Actually, the readOnly=true makes things worse.
What it does (among other things) is:

which leads to:

Try readOnly="true" in the dataSource configuration. This causes several
defaults to get set in the JDBC connection, and often will solve problems like

Something like this? q=title:(1* 2* 3* 4* ... 9*)&q.op=OR

Hi all,
It seems that DIH always holds two connections open to the database.
One of them is almost always 'idle in transaction'. It may sometimes
seem to do a little work but then it goes idle again.
