One embodiment of the present invention provides a system that facilitates user queries to a database. During operation, the system stores one or more query criteria templates in a template table in the database. Each record in the template table corresponds to a query criteria template. A query criteria template contains information on search-field names and search-field values for a query. The system also allows a user to select a template from the stored templates prior to performing a query, thereby reducing the number of search-field values the user has to manually enter. In this way, a number of query criteria templates can be stored in a single table with a column containing parsable query criteria.
