The slaves should be constantly available, meaning searching performance

We found that optimising too often killed our slave performance. An optimise

Hi,
We're building quite a large shared index of resources, using Solr. The
application that makes use of these resources is a multitenant one

Hi,
Do you have any kind of "group" membership for you users? If you have, a
resource's list of security access tokens could be smaller and avoid
re-indexing most resources when adding "normal" users which mostly belong to
groups. The common way is to add filters on the query. You may do it you

Im using trunk and FVH and eventhough I filter stopwords when searching, I
would like to highlight stopwords in fragments. Using a different field

Is there a way to do this?

First, as Andrew says, optimizing will force a complete

It's because lowernames=true by default in solrconfig.xml, and it will convert

another way is to store the original hierarchy in a sql database (in
the form: id, parent_id, name, level) and in the Lucene index store
the complete
hierarchy (from root to leave node) for each document in one field
using the ids of the sql database. In that way you can get documents
