Performance different if searching on normal or keyword field?

[asp]

Ok, thanks a lot. I also thought in this direction, but I wanted to be sure

Then I have one additional question which is enhancing the original one.

I opnened a different thread for it, but I assume I can answer it with the details you provided:

Optimize search speed / resource usage by writing good queries?

Hi, I would like to increase my the search speed in kibana. Since I am not that familar with lucene indexes / elasticsearch yet, I would like to ask you for your opinion. Searching is real easy via kibana. Just type in a word and all events containing the word are given back. Now my events have several fields, just like type, payload, message, username, etc. For example, if I am searching for a username, does it improve the speed if I search for: username: xyz instead of searching for xyz? …

So if my event has multiple fileds: message, payload, field 1... field n, then it should be faster to name the fields I am searching in, and even faster if I can filter on the keyword field. correct? Because there is one inverted index per field?

Thanks, Andreas
