Hi , I noticed that in MLT API , we can mention the fields to compare (mlt\_fields) while in MLT query , we can only give a like\_text.Using this field , i can ask ES to compare A,B,C fields of the feed in question against the feed that it compares to. Can i emulate the same with MLT query too. I have a feed and i dont want to index it for searching. Rather , i want to find its MLT matching without indexing. Say i want to compare fields A,B,C using the MLT query , is that possible ? Thanks Vineeth -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
