Some people may be relying on the fact that the URL is analyzed for their searching. I suggest we make this a multi-field so that there are http.url (text) and http.url.keyword (keyword) fields. Here's an example.

beats/auditbeat/_meta/fields.common.yml

Lines 23 to 31 in 4cbb1de

	- name: path
	type: text
	description: The path to the file.
	multi_fields:
	- name: raw
	type: keyword
	description: >
	The path to the file. This is a non-analyzed field that is useful
	for aggregations.

[perjahn]

Sure. Try 2.

[andrewkroh]

LGTM. Can you please add an entry to the CHANGELOG.asciidoc file.

[perjahn]

Should be done. (there was some strange character on line 2391 in the asciidoc file, Cache: optional...)

@perjahn Can you run make update in the heartbeat directory to update the auto generated files?

[perjahn]

Sorry, having some problems with my environment.

[ruflin]

Let us know if we can help.

[kvch]

jenkins test it

[tsg]

@perjahn This is close to being merged, if you want, we can either send you a PR to your branch after running make update, or take over the commits in a new PR.

[perjahn]

Yes, please take over the commits.

[ruflin]

I took the PR over here: #6479

@perjahn Thanks for your work on this one.
