Hi all, I'm working on a project where we have to do searches that are a combination of traditional searches of the kind that ES handles well, plus other types of queries that use a specialized index that we'd like to maintain separately. Is it possible/advisable to write a plugin or something that could dispatch parts of queries to external indices, parse the results and merge them with the ES part of the query? I tried to look around the ES plugin documentation to see what hooks were there, but I couldn't tell if any of them allowed delegating whole parts of the query and then merging at the end. Thanks for your help! Ben -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
