khard.query.parse(string: str) → Union[TermQuery, FieldQuery]

Parse a string into a query object

The input string interpreted as a FieldQuery if it starts with a valid property name of the CarddavObject class, followed by a colon and an arbitrary search term. Otherwise it is interpreted as a TermQuery.

Parameters

string – a string to parse into a query

Returns

a FieldQuery if the string contains a valid field specifier, a TermQuery otherwise
