Re: Does DocValues improve Grouping performance ?

[Mikhail Khludnev]

Oh my. Sorry SOLR-5662  is
a duplicate for SOLR-5882, where the patch exists. I appreciate if someone
from committers can nail it down.

import community cassandra into solr

[Tim Dunphy]

Hey folks,

 Is there any way that we know of to import the open source Apache version
of the Cassandra database into Solr? I know that the pay for Datastax
version has a connection built in. But we're not using that.

Any thoughts or observations will be appreciated.

Thanks,
Tim

CopyField exclude patterns

[danny teichthal]

Hi,
Is there a way to make some patterns to be excluded on the source of a
copyField?

We are using globs to copy all our text fields to some target field.
It looks something like this:


I would like a subset of the fields starting with "prefix_" to be excluded
and not copied to destination. (e.g. all fields with "prefix_abc_*" ).
Is there a way to do it on SOLR?

I couldn't find anything saying that it exists.

Thanks
