Add bookmarks search

[SamSamskies]

Is your feature request related to a problem? Please describe. If you bookmark a lot of notes, it can be hard to find what you're looking for. The filter by user is nice, but a lot of the time it's hard to remember who posted the note you're looking for.

Describe the solution you'd like Add a search input that does a fuzzy search on the note contents as the user types in the input would be nice.
