feat: add basic search functionality

[Jesperpaulsen]

This PR introduces basic search functionality by doing a simple string matching for a given field.

Was a bit unsure about the naming convention for stuff I introduced, as I normally would have called it something related to query. However, since we're adding a "query" to an already defined query, I tried to stay away from calling the variables something with query.

Haven't contributed that much to open source before, so let me know if there is anything I should change. Have realized it probably should have been called custom filter instead of search functionality?

Not an issue at all, opening this PR is the right direction 🤠. I'll leave a review and we can get this going. Thanks for contributing!

this is looking really good! I left some comments (mostly stylistic to match existing conventions) but besides i'm willing to merge this 🎉

thanks for contributing

Awesome, thanks a lot for the great feedback @ricokahler 🤠 🙇 Will go through and fix the code. What will be the correct commit message type for angular commit messages when fixing the feature? Refactor?
