Re: Using Multiple Cores for Multiple Users

So, if my other filter/selection criteria get some set of the whole index that goes say from 50% relevance to 60% relevance, the set still gets ordered by relevance and then each item in the returned set is still based on its relevance relative to the set, right? That would only be a problem if

Re: Using Multiple Cores for Multiple Users

Relevance is TF/DF, meaning the term frequency in the index. DF is the number of times the term appears in the document. There is no quick calculation for "total frequency for terms only in these documents". Facets do this, and they're very very slow. On Tue, Nov 9, 2010 at 7:50 PM, Dennis Gearon

Re: Highlighter - multiple instances of term being combined

Have you looked at solr/admin/analysis.jsp? This is 'Analysis' link off the main solr admin page. It will show you how text is broken up for both the indexing and query processes. You might get some insight about how these words are torn apart and assigned positions. Trying the different Analyzers

There is a standard problem with this: relevance is determined from all of the words in a field of all documents, not just the documents that match the query. That is, when user A searches for 'monkeys' and one of his feeds has a document with this word, but someone else is a zoophile, 'monkeys' wi

Re: solr init.d script

As many solrs as you want can open an index for read-only queries. If you have a shared disk with a global file system, this could work very well. A note: Solr sessions are stateless. There is no reason to run JBoss Solr in fail-over mode with session replication. On Tue, Nov 9, 2010 at 12:25 PM,

Thanks a lot for all the tips, guys! I think that we may explore both options just to see what happens. I'm sure that scalability will be a huge mess with the core-per-user scenario.

RE: Using Multiple Cores for Multiple Users

If storing in a single index (possibly sharded if you need it), you can simply include a solr field that specifies the user ID of the saved thing. On the client side, in your application, simply ensure that there is an fq parameter limiting to the current user, if you want to limit to the curren
