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?
I mean, now ES would know, that it only needs to search within that field, but I am not sure, if the indexing is based on fields or on top level of the document.
I just want to optimize my saved queries and want to give the other team members hints to query as resource nicest as possible
I am aware of the fact, that I may get also additional events, where the username may occur in a different filed, if not setting the filter for the name. Just think of an example where xyz is ONLY found in the username.
