is EmbeddedSolrServer thread safe ?

at SolrJ wiki page : http://wiki.apache.org/solr/Solrj#EmbeddedSolrServer CommonsHttpSolrServer is thread-safe and if you are using the following constructor, you *MUST* re-use the same instance for all requests. ... But is it the same for EmbeddedSolrServer ? Best regards Jean-François

Re: Ram Index

There is a DirectoryFactory in Solr that could be used to make Lucene's RAMDirectory. But then you'd have to reindex everything when restarting Solr. Doesn't seem to make much practical sense to use it, not even for performance reasons thanks to Lucene and Solr both caching what they

Nested phrases with proximity in Solr

Hello, As far as I've been able to dig up, there is no way to use nested phrases in Solr, let alone with proximity. For instance a b c d~10. I've seen a special Surround Query Parser in Lucene that appears to support this. Am I missing something? Any clues anybody? Thanks in advance, bye,

RE: Too Many Boolean Clauses

Is a filter really appropriate in this case? These types of condition would never get re-used - they would be unique to each search performed by users in our application. Is there any performance benefit to the filter aside from caching (which wouldn't do much for us anyway)? -Original

Re: Too Many Boolean Clauses

Hmm - yeah - coming at that a bit from the Lucene perspective - you wouldn't want it cached. For a ton of clauses like that, a filter can outperform a booleanquery on a large index in certain cases (an uncached filter). And doesn't suffer from having to mess with the max clause setting. Thats part
