Abstract
A query comprising of sub queries, each of which could be of different media types are used to search a collection of multimedia documents in a database. These sub queries are parsed according to media type and operators/functions between these sub queries are recorded creating a set of query objects and query operator objects. The query interface than passes the query objects to the appropriate application programming interfaces (API's) of the various search engines. Furthermore, it applies the query object operators to the respective interim results obtained by executing a query object. Then the interim results are combined in a global result object that is processed using a user specification to produce a single combined result list that conforms to user specified requirements.
