Dynamic Operators & Fields on query record.

I have a requirement where the user can select the 5 mutliple dropdown values,Sort for any one of 5 and operators for each value from operator dropdown and Gate operator (AND or OR).

Ex:
Employee Dept(dropdown) Sort On(radio button) Operator(dropdown) Gate
Medical Yes = AND
Transport No is null OR
Finance No includes AND
Billing No = OR
Delivery No in AND

based on the user selected values I would required a query record with selected employee depts as fields in the filters with respective operators.

Can someone please provide your valuable suggestions to write queryrecord.

Thanks in Advance.
