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?](https://discuss.elastic.co/t/optimize-search-speed-resource-usage-by-writing-good-queries/78695): > > 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 --- _[View the full topic](https://discuss.elastic.co/t/performance-different-if-searching-on-normal-or-keyword-field/78692)._
