PROBLEM TO BE SOLVED: To provide free text and attribute searching of electronic program guide (EPG) data. SOLUTION: Subject matter includes a search engine for electronic program guide (EPG) data and related methods. In an exemplary method, a text search string can be normalized into searchable terms and the terms interpreted as either text search terms or attribute search terms. One or more queries having search conditions of varying degrees of complexity are created according to the interpretation of the terms of the search string. One or more searches in EPG databases and/or web-resources are performed based on interpretation of the text and attribute terms and results are given a relevancy ranking according to the interpretation. The combined search results may be grouped, ranked and filtered for display to the user. Results may also be displayed progressively as each character of a search string is entered by the user.
