OS X comes with a framework called SearchKit that applications can use to index content and support full-text searches. I occasionally run into situations where I want to take advantage of an application’s existing SearchKit index so that I can perform my own full-text searches programmatically. The most recent case arose this weekend while I was attempting to build an Alfred workflow for searching Quiver notes. Quiver uses SearchKit internally to expose full-text search through its own user interface, but it doesn’t have native Spotlight integration yet.
