CcLowerPath (4 bytes): A 32-bit unsigned integer containing the number of Unicode characters in the _lowerPath field.
_lowerPath (variable): A non-null-terminated Unicode string representing the path to which the query is restricted. The CcLowerPath field contains the length of the string.
_padding (variable): This field MUST be 0 to 3 bytes in length. The length of this field MUST be such that the following field begins at an offset that is a multiple of 4 bytes from the beginning of the message that contains this structure. If this field is present (that is, length nonzero), the value it contains is arbitrary. The content of this field MUST be ignored by the receiver.
_length (4 bytes): A 32-bit unsigned integer containing the length of _lowerPath in Unicode characters. This MUST be the same value as CcLowerPath.
_fRecursive (4 bytes): A 32-bit unsigned integer. MUST be set to one of the following values:
Value
|
Meaning
|
0x00000000
|
The server is not to examine any subdirectories.
|
0x00000001
|
The server is to recursively examine all subdirectories of the path.
|
_fVirtual (4 bytes): A 32-bit unsigned integer. MUST be set to one of the following values:
Value
|
Meaning
|
0x00000000
|
_lowerPath is a file system path.
|
0x00000001
|
_lowerPath is a virtual path (the URL associated with a physical directory on the file system) for a website.
|
CSort
The CSort structure identifies a column, direction, and locale to sort by.

pidColumn
|
dwOrder
|
dwIndividual
|
locale
|
pidColumn (4 bytes): A 32-bit unsigned integer. This is the index in CPidMapper for the property to sort by.
dwOrder (4 bytes): A 32-bit unsigned integer. MUST be one of the following values, specifying how to sort based on the column.
Value
|
Meaning
|
QUERY_SORTASCEND
0x00000000
|
The rows are to be sorted in ascending order based on the values in the column specified.
|
QUERY_DESCEND
0x00000001
|
The rows are to be sorted in descending order based on the values in the column specified.
|
dwIndividual (4 bytes): A 32-bit unsigned integer. dwIndividual specifies how to treat properties of type VT_VECTOR with regard to sorting and MUST be one of the following values.
Value
|
Meaning
|
QUERY_SORTALL
0x00000000
|
The complete property is used for sorting, resulting in a single row for each result.
|
QUERY_SORTINDIVIDUAL
0x00000001
|
Each element of the VT_VECTOR is used for sorting independently, possibly resulting in multiple rows for a single result.
|
locale (4 bytes): A 32-bit unsigned integer indicating the locale (as specified in [MS-LCID]) of the column. The locale determines the sorting rules to use when sorting textual values. The GSS can use the appropriate operating system facilities to do this.
CVectorRestriction
The CVectorRestriction structure contains a weighted OR operation over restriction nodes. Vector restrictions represent queries using the full text vector space model of ranking (see [SALTON] for details). In addition to the OR operation, they also compute a rank based on the ranking algorithm.

|
_pres (variable): A CNodeRestriction command tree upon which a ranked OR operation is to be performed.
_padding (variable): This field MUST be 0 to 3 bytes in length. The length of this field MUST be such that the following field begins at an offset that is a multiple of 4 bytes from the beginning of the message that contains this structure. If this field is present (that is, length is nonzero), the value it contains is arbitrary. The content of this field MUST be ignored by the receiver.
_ulRankMethod (4 bytes): A 32-bit unsigned integer specifying a ranking algorithm. MUST be set to one of the following values.
Value
|
Meaning
|
VECTOR_RANK_MIN
0x00000000
|
Use the minimum algorithm, as specified in [SALTON].
|
VECTOR_RANK_MAX
0x00000001
|
Use the maximum algorithm, as specified in [SALTON].
|
VECTOR_RANK_INNER
0x00000002
