Defined in:

#fuzzy_filter_items(items, query, case_type: :smart) ⇒ Items

Use fzf to filter an Items object with a search query. Faster than #filter_items when all you need is a text search of the title and note

Parameters:

  • items (Items) —

    an Items object

  • query (String) —

    The search query

  • case_type (Symbol) (defaults to: :smart) —

    The case type (:smart, :sensitive, :ignore)

Returns:

  • (Items) —

    Filtered Items array
