It is possible to exclude individual notes (and agents) by setting an item-scope Boolean $Searchable. By setting a false value, that item is excluded from searches even if otherwise matching search criteria. This makes it easier to exclude behind-the-scenes notes like templates, prototypes, and general framework containers for normal searches whist allowing content to be intermingled. Previously, such items were excluded by storing them away from primary content in a different outline branch or map.
The attribute affects notes, containers, agents and aliases (see below). Adornments are always excluded, regardless of the $Searchable setting.
The attribute is intrinsic so may be set separately for aliases, for instance ensuring a particular alias is matched rather than its original.
