Text Analysis Keys

Each of these constants is an optional key in a Search Kit index’s text analysis properties dictionary. The constant descriptions describe the corresponding values for each of these keys. These keys are declared in the Analysis.h header file.




The minimum term length to index. Specified as a CFNumber object. If this optional key is not present, Search Kit indexing defaults to a minimum term length of 1.


A set of stopwords—words not to index. Specified as a CFSet object. There is no default stopword list. You must supply your own.


A dictionary of term substitutions—terms that differ in their character strings but that match during a search. Specified as a CFDictionary object.
