Property Searches (Constructing Search Strings)

In addition to the literal page text, Search & Preview also collects metadata about each page. You can search for specific values for specific types of metadata by entering a property name and value separated by a suitable operator (such as:, =, <, >, etc.). For example, “ author:‘Douglas Coupland’ “ will find a document written by the named author.
See “Property Search Syntax” for a complete list of available properties and the operators and another syntax available for searching in each of them.
