Search for items matching the attributes in the collection.
The attributes should be a table of string keys and string values.
If secret_search_all is set in flags, then all the items matching the search will be
returned. Otherwise only the first item will be returned. This is almost always the unlocked item that was most recently stored.
If secret_search_unlock is set in flags, then items will be unlocked if necessary. In
either case, locked and unlocked items will match the search and be returned. If the unlock fails, the search does not fail.
If secret_search_load_secrets is set in flags, then the items will have their secret
values loaded and available via [method@Item.get_secret].
This function returns immediately and completes asynchronously.
