Type (4 bytes): A 32-bit unsigned integer indicating the restriction type used for the command tree node. The type determines the format and interpretation of the Restriction field of the structure, as specified in the following table. This field MUST be set to one of the values listed in the following table.
|
Value |
Meaning |
|---|---|
|
RTAnd 0x00000001 |
The node contains a CNodeRestriction on which a logical AND operation is to be performed. |
|
RTOr 0x00000002 |
The node contains a CNodeRestriction on which a logical OR operation is to be performed. |
|
RTContent 0x00000004 |
The node contains a CContentRestriction. |
|
RTProperty 0x00000005 |
The node contains a CPropertyRestriction. |
|
RTProximity 0x00000006 |
The node contains a CNodeRestriction with an array of CContentRestriction structures. Any other kind of restriction is undefined. The restriction requires the words or phrases found in the CContentRestriction structures to be within a query server defined range to be a match. The query server can also compute a rank based on how far apart the words or phrases are. |
|
RTNatLanguage 0x00000008 |
The node contains a CNatLanguageRestriction. |
|
RTPropertyRange 0x0000001C |
The node contains a CPropertyRangeRestriction. |
|
RTDocSet 0x00000019 |
The node contains a CDocSetRestriction. |
|
RTInternalProp 0x00000016 |
The node contains a CInternalPropertyRestriction. |
|
RTExactWord 0x00000018 |
The node contains a COccRestriction. |
|
RTSynonym 0x00000012 |
The node contains a COccRestriction. |
|
RTRange 0x00000014 |
The node contains a CRangeRestriction. |
|
RTScope 0x0000001A |
The node contains a CScopeRestriction. |
|
RTPhrase 0x00000013 |
The node contains a CNodeRestriction. |
|
RTNot 0x00000003 |
The node contains a CNotRestriction. |
|
RTWord 0x00000011 |
The node contains a COccRestriction. |
|
RTProb 0x0000000D |
The node contains a CNodeRestriction |
|
RTScopeRange 0x0000001D |
The node contains a CScopeRangeRestriction. |
SubType (4 bytes): A 32-bit unsigned integer that specifies the inclusion behavior for child restrictions of a CProbRestriction. Child restrictions are restrictions stored in the Restrictions array of a CNodeRestriction whose Type field value is RTProb. This value of the field MUST be set to zero ("0") and MUST be ignored for all other restrictions. The value MUST listed in the following table.
|
Value |
Meaning |
|---|---|
|
rstUndefined 0x00000000 |
The inclusion behavior does not apply to this type of restriction (1). |
|
rstInclude 0x10000000 |
Documents that match this restriction MUST be returned unless they do not match one of the restrictions with SubType rstMustInclude or match any of the restrictions with SubType rstExclude among the child restrictions of the restriction’s parent CProbRestriction. |
|
rstMustInclude 0x20000000 |
Documents that do not match this restriction (1) MUST NOT be returned. |
|
rstExclude 0x30000000 |
Documents that match this restriction (1) MUST NOT be returned. |
Weight (4 bytes): A 32-bit unsigned integer representing the weight of the node. Weight indicates the node's importance relative to other nodes in the query command tree. Higher weight values are more important.
Restriction (variable): The restriction type for the command tree node. The format MUST be as indicated by the Type field.
