Description :

Field-level query information is stored in a CDQUERYBYFIELD record in fields of type TYPE_QUERY, usually the query field of an Agent. The query field of an Agent is used to select documents to be operated on by the Agent. This record consists of this data structure, followed by the field name and any value for the field query (in packed format). The fields in this structure are:


      Header Defines this composite data item as a CDQUERYBYFIELD item.
      dwFlags Field query flags (see QUERYBYFIELD_FLAG_xxx).
      wDataType Type of field to search (see TYPE_xxx).
      wOperator Field query operation (see QUERYBYFIELD_OP_xxx).
      Date1 First TIMEDATE value for comparison.
      Date2 Second TIMEDATE value defining a range.
      Number1 First ALIGNED_NUMBER value for comparison.
      Number2 Second ALIGNED_NUMBER value defining a range.
      wFieldNameLen Length of the field name.
      wValueLen Length of the value.

    This structure is followed by a packed string containing the field name and any field value.
