Feature request: Ability to filter memos

[marrobHD]

It would be useful to have the ability to filter memos by text. An ability to search all memos by cameras in a certain defined timespan for keywords. Keyword presets would also useful.
For example: With a click you could search last week's memos for the keyword "dog". With another click you could search last week's memos from camera frontdoor for the keyword "amazon-parcel"
