If I use the search type "dfs_query_then_fetch", as I understand it the first step of the search is to go to each of the shards collecting the inverse document frequencies.
If I was searching across multiple indexes, would it collect the idfs from each of the indexes and combine them? E.g. if I randomly split an index in half (e.g. "unsecured" and "secured"), if I did a search across both of those indexes, would the results (and their scores) be roughly similar to if I had all the documents in one index and just did the search on that? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
