ATG Search represents index item metadata as properties stored with the index item. During a query, ATG Search can restrict its search to items with certain property values. Numeric property values can be tested for equality, less-than, and greater-than. String property values can test for sub-string matches, and both types can be tested for range matches. The XML representation for these constraints is:
<prop type="type" name="name" op="str_op|num_op" case="true|false">value
</prop>
<strprop name="name" op="str_op" case="true|false">value</strprop>
<numprop name="name" op="num_op" >value</numprop>
The constraints are:
type is one of six possible property types,
enum,string,float,integer,booleananddate. Thestrpropconstraint is equivalent to the type values ofenumandstring, and thenumpropconstraint is equivalent to the other four type values.nameis the name of the property.valueis the operand value for the constraint.The
opattribute contains the comparative operator for the constraint, which defaults toequal.
All constraints allow the following operators:
equal – the index item must have a property value equal to the operand
greater – the index item must have a property value greater than the operand
greatereq – the index item must have a property value greater than or equal the operand
less -- the index item must have a property value less than the operand
lesseq -- the index item must have a property value less than or equal the operand
between – the index item must have a property value between the operand range values exclusively, expressed as initial-final.
within – the index item must have a property value between the operand range values inclusively, expressed as initial-final.
For string and enum property constraints, the comparisons are character byte comparisons. In addition, the enum and string property constraints allow three more operators:
contains – the index item must have a property value that contains the operand
starts – the index item must have a property value that starts with the operand
ends – the index item must have a property value that ends with the operand
For string property constraints, the additional case attribute controls whether the operator should be case-sensitive (true) or case-insensitive (false). If the operator is a range operator, then the value is a range of values expressed as initial-final.
