We are encountering this Reducesearchphaseexception for a long period, when we use the search type dfs_query_then_fetch. We are waiting for this to be fixed ASAP.
We have requested for a fix in the earlier thread http://elasticsearch-users.115913.n3.nabble.com/quot-dfs-query-then-fetch-quot-search-type-returns-Error-td3062523.html#a3113866 , where we did not got any response from you.
Can we expect this issue to be fixed in the upcoming ES 0.17.0 fix? We are facing lot of problem with this and unable to face our clients, because searching is the most important feature in our application.
Kindly provide us a fix in 0.17.0 version.
