Resolution:
While using the literal match condition, the condition will be specified as:
_Eval(“&ltcondition>”) where &ltcondition> is the same as the syntax you use while querying through the Siebel client.
For example, if you have a simple query with an OR condition, you can add this string in the literal match for the Business Component field.
    _Eval(" [C1] = "xxx" or C2 = "yyy" ")
where C2 is the Business Component field for which the search parameter is added and C1 is another Business Component field.
Kindly refer to the Siebel book shelf for details on specifying _Eval conditions.
