Prometheus: Search pattern for metrics in query box, doesnt search whole word rather it search for each letter of the word

[kavyakul]

What did you do?
Search metrics in Prometheus

What did you expect to see?
name of the metric matching the pattern

What did you see instead? Under which circumstances?
the word was not matched as a whole, rather each letter was searched.

Environment

• System information:
  Docker container running on Linux 3.10.0-514.26.2.el7.x86_64 x86_64

• Prometheus version:
  Prometheus docker image version: v1.7.1

I'd not restrict the input to whole word matches, but assuming org_graylog2_memory is an existing metrics name/prefix, it should surely show up at the top.

Maybe @stuartnelson3 can port his weight algorithm from alertmanager over?

Can try to take a look if I have time this weekend.
