Hi, I have created summary index using collect command and in summary index my actual host, source field gets converted into orig_host, orig_source resp. Now I want to know is there any concept of metadata for summary index like in normal index host,source,_time are default index-time extarcted fields and using host/source the search results become faster since it searches only those bucket containing searched host/source. similarly is there any concept in summary index? Or in summary index all fields are index-time extracted fields? Any guidance would be appreciate.
