Advanced search

Allow users to have advnced search. Some suggestions are:
— Allow filtering by app, time, date, etc…
— Regex support
— Seach by text lenght (greater than, less than, or equal to)

Would love to be able to search a specific pinboard, like “Saved”.

Don’t know how search works currently, but I can’t even search by substring right now.

can be considered with #57

the rule clipping folder can be seen as a subscription to the search results.
