queryOptions.applicationSearchFilter = string;Public Property ApplicationSearchFilter As StringProperty Value
A simple keyword, or a string that conforms to Advanced Query Syntax (AQS). For more information, see Using Advanced Query Syntax Programmatically.
Remarks
The application search filter should always use locale-invariant Advanced Query Syntax (AQS) syntax (such as System.FileName instead of "filename" (because the term "filename" that is associated with the property System.FileName is localized differently in different languages). This will ensure that the query returns the expected results on systems with non-English locales. Windows builds the search query by combining this property with the UserSearchFilter property.
