Searching / Filtering on multiple tags

[FinaleWu]

Problem
Just purchased from App Store. Like the intuitive UI and performant experience. Very promising!

Is there any chance to support filtering on multiple tags? Say, searching for books with BOTH tag:Fiction AND tag:Mystery.

Idea
Operators like NOT, OR; Modifiers like parenthesis (grouping), quotation (exact match), before:/after: (published before/after given date)are nice to have.

Dynamic hit count with autocomplete prediction can be a cool feature too (using iPhone Photo app’s search UI as an example).

Boolean operators (AND, OR, NOT) are a possibility. I'll look into those.

Autocomplete/hit count doesn't seem likely. I get that it's a nice feature, but I'm unfortunately just one person, not a team at Apple.
