I want to build search criteria by using SPQuery object that searches a list. On application page, there are two textbox Controls, 2 combobox Controls and 2 people picker Controls. The search criteria is based on user input. Users will use any or all of these Control values to search records. I could not find an efficient way to solve this issue. I need some good links or suggestion to solve this.
