: As for the second part, I was thinking of trying to replace the standard : SolrIndexSearcher with one that employs a MultiSearcher. But I'm not very : familiar with the workings of Solr, especially with respect to the caching : that goes on. I thought that maybe people who are more familiar with it might : have some tips on how to go about it. Or perhaps there are reasons that make : this a bad idea.
If your indexes are all local, then using a MultiReader would be simpler trying to shoehorn MultiSearcher type logic into SolrIndexSearcher. https://issues.apache.org/jira/browse/SOLR-243 -Hoss
