Search operations.

For the key bindings implementation with attached filters, check
`prompt_toolkit.key_binding.bindings.search`. (Use these for new key bindings
instead of calling these function directly.)

    A search 'query', associated with a search field (like a SearchToolbar).

    Every searchable `BufferControl` points to a `search_buffer_control`
    (another `BufferControls`) which represents the search field. The
    `SearchState` attached to that search field is used for storing the current
    search query.

    It is possible to have one searchfield for multiple `BufferControls`. In
    that case, they'll share the same `SearchState`.
    If there are multiple `BufferControls` that display the same `Buffer`, then
    they can have a different `SearchState` each (if they have a different
    search control).
