This property specifies the property set GUID and, with the PropPid property, uniquely identifies this column for indexing, search and retrieve purposes.
Syntax
IColumn.PropGuid
Remarks
The value of PropGuid is a Microsoft GUID string, such as:
49691c90-7e17-101a-a91c-08002b2ecda9
In order for indexing and search to function for this column, the PropGuid and PropPid properties must match properties emitted by filters for the expected document types.
The combination of the PropGuid and PropPid properties must be unique in the Search schema (the comparison is not case-sensitive). Search does not check that the pair of values is unique until you call the ISearchSchema.Save method.
Example
