Execution of Queries in Parallel: geotagged textual documents in Solrvvvv

[Massimiliano Ruocco <ru...@idi.ntnu.no>]

I have around 100M of textual document geotagged (lat,long). THese 
documents are indexed with Solr 1.4. I am testing a retrieval model 
(written over Terrier). This model requires frequent execution of 
queries ( Bounding-box filter). These queries could be executed in 
parallel, one for each specific geographic tile.

I was wondering if exists a solution speeding up the execution of 
queries in parallel. My naif idea is Split the index in many parts 
according the geographical tiles (how to do that? SolrCloud? Solr Index 
Replication? What is the max number of eventual replication?)

Any practical further suggestion?

Thanks in advance

Massimiliano

: I'd move to SolrCloud 4.2.1 to benefit from sharding, replication, and
: the latest Lucene.  How many queries you will then be able to run in
: parallel will depend on their complexity, index size, query
: cachability, index size, latency requirements... But move to the
: latest setup first.

No to mention thta geospatial query support is vastly improved in Solr 4.x 
vs what was possible in Solr 1.4.

Hi,

I'd move to SolrCloud 4.2.1 to benefit from sharding, replication, and
the latest Lucene.  How many queries you will then be able to run in
parallel will depend on their complexity, index size, query
cachability, index size, latency requirements... But move to the
latest setup first.
