A method and system for automatic distributed tuning of search engine parameters includes receiving a search parameter at a search engine. The search engine is equipped with a plurality of tunable knobs set at an initial setting. The search parameter is quantified by the initial setting of the plurality of tunable knobs. A search result is generated for the search parameter based on the initial setting of the plurality of tunable knobs. The search result includes a plurality of result objects. The search result is presented by the search engine. One or more result objects selected from the search result over time, is determined. The plurality of tunable knobs in the search engine are automatically tuned using one or more search algorithms to obtain optimal search result based on the selection of the result objects over time.
