Search bundles are bundles to provide search results for Spotlight. There is a hardcoded limit of 11 (for iOS 8 and below, unknown for iOS 9) search bundles (domains), all of which are occupied by built-in ones.
SearchLoader is a developer library for adding more search bundles.

Finding a Search Domain
[[%c(SPUISearchModel) sharedInstance] searchDomains] will list all the domains
[[%c(SPDomainManager) defaultManager] getBundleIdForDomainNumber:] will then give you their bundle ids
Categories
In iOS 9, search have a combination of categories, bundle id, domains, and display identifiers. For example, Top hits has a category of com.apple.spotlight.tophits domain of 0 and display identifier of DOMAIN_TOPHIT
Structure of a Search Bundle
Search bundles should have an extension of .searchBundle. The principle class should conform to the SPSearchDatastore protocol.
