Search improvements: exact matching and multiple filters

[sule26]

First of all, I would like to congratulate you on the awesome project. I've just switched from k9s, and I've been liking it a lot so far.

That said, I would like to suggest some improvements to the search functionality.

Right now, it seems that the search does not work quite as I would expect. For example, when I search for istiod in my cluster, it also matches other pods that have istio in the name plus a d somewhere else in the pod name. For example, it matches istio-cni-node-*.

I think it would be useful if the search could prioritize or support exact/substring matching, so that searching for istiod would only match resources containing istiod as a contiguous string.

The other thing is that it doesn't seem to be possible to filter for more than one thing at a time. For example, in k9s, something like:

istiod|istio-cni-node

works and allows me to filter for multiple values at the same time.

I think supporting something similar would be very helpful, especially when you want to quickly narrow down resources matching multiple names or patterns.

Thanks again for the great project!

Thanks, glad you like it! Both are fixed in #696, lands in the next release :)

• istiod now matches only names containing istiod as a contiguous string. Plain text is a case-insensitive substring match by default, ~istiod if you ever want the old fuzzy match
• istiod|istio-cni-node works like in k9s. Names can't contain |, so a bare | always means "or". Works with labels too - label:api|worker

Until the release, "istiod" and /istiod|istio-cni-node/ already do this on the current version.
