Query Property Set

[This is preliminary documentation and subject to change.]

The query property set contains properties computed or made available by the query engine in Index Server. The GUID is PSGUID_QUERY, which is defined in oledb.h as:

extern const GUID PSGUID_QUERY = {0x49691c90,0x7e17,0x101a,{0xa9,0x1c,0x08,0x00,0x2b,0x2e,0xcd,0xa9}};
 

Some of these properties are defined in oledb.h, the rest in ntquery.h.
