Chris Male commented on SOLR-773: --------------------------------- >From my experience more than just a FunctionQuery is required for LocalSolr to >be efficient. Without the Cartesian tier information that is added by the >UpdateProcessor, you will have to calculate the distance for every single >document in our index. The great circle distance calculations are actually >quite expensive and when multiplied by say 1 million documents, the query time >will become around 2 or 3 seconds. If you then repeat the calculation again >for sorting on distance, then the time will be even worse. Therefore it seems >necessary to include some way to reduce the number of distance calculations >that are done. > Incorporate Local Lucene/Solr > ----------------------------- > > Key: SOLR-773 > URL: https://issues.apache.org/jira/browse/SOLR-773 > Project: Solr > Issue Type: New Feature > Reporter: Grant Ingersoll > Assignee: Grant Ingersoll > Priority: Minor > Attachments: exampleSpatial.zip, lucene-spatial-2.9-dev.jar, > lucene.tar.gz, SOLR-773-local-lucene.patch, SOLR-773-local-lucene.patch, > SOLR-773-local-lucene.patch, SOLR-773-local-lucene.patch, > SOLR-773-local-lucene.patch, SOLR-773-spatial_solr.patch, SOLR-773.patch, > SOLR-773.patch, spatial-solr.tar.gz > > > Local Lucene has been donated to the Lucene project.
