I have created an engine that combines searches from the major search engines to create a refined list of results. Main searches restrict the number of results to on average a thousand for the general public or non API subscribed people. I was wondering if anyone had ideas on how to maximize the results from lets say Google where the actual query is manipulated to perhaps bring back more results. For example if I were to search by a specific date range, then I could perhaps periodically change the range by creating multiple ranges within the initial set of date range. Appreciate any response.
