16. A system for automatic distributed tuning of search engine parameters, comprising: a computer system, the computer system including a user interface configured to receive a search parameter; and a search engine with a program stored in a computer memory, which when executed by the computer system performs automatic distributed tuning of search engine parameters, the program includes logic to, interact with the user interface to receive the search parameter, the search engine equipped with a plurality of tunable knobs set at an initial setting; generate a first search result for the search parameter based on the received search parameter and the initial setting of the plurality of tunable knobs, automatically adjust setting of one or more of the plurality of tunable knobs to a second setting; generate, using a microprocessor, a second search result for the search parameter based on the received search parameter and using the second setting of the plurality of tunable knobs, wherein the first and second search results include a plurality of result objects; combine, using a microprocessor, the plurality of result objects from the first search result with the plurality of result objects from the second search result to generate a combined search result; forward the combined search result with the plurality of result objects to the user interface; receive a selection of one or more of the result objects over time from the user interface, the selection of one or more result objects identifying associated tunable knobs; and select, using a microprocessor, one of the two tunable knob settings to be retained as the initial setting for a subsequent search, the selection of one of the two tunable knob settings based on the selection of one or more result objects over time, the selected tunable knob setting provides an optimal search result for the search parameter.
17. The system for automatic distributed tuning of search engine parameters of claim 16 , wherein the user interface further including an input device to, receive the search parameter; select one or more result objects; and a display device to display the combined search result upon receiving the combined search result from the search engine.
