4. The method of claim 1 further comprising: identifying a language model based on at least one characteristic associated with the user, and wherein the deriving one or more recognition hypotheses includes: using the identified language model to derive the one or more recognition hypotheses. 5. The method of claim 1 wherein the query parameters include the determined length of the longest pruned recognition hypothesis, a value representing a total number of terms to be included in a query, and a value representing a proportion of new terms added from a first recognition hypothesis to a second recognition hypothesis. 6. The method of claim 1 wherein the query parameters vary by user or user group. 7. The method of claim 1 wherein the providing results of the search system includes: adjusting a ranking of the results of the search system based on the weights. 8. The method of claim 1 wherein the providing results of the search system includes: organizing the results based on the weights. 9. The method of claim 1 further comprising: discarding, prior to constructing the weighted boolean query, those recognition hypotheses associated with a weight below a threshold value. 10. The method of claim 1 wherein the weighted boolean query is a weighted OR-query. 11. The method of claim 1 further comprising: refining the weighted boolean query based on the results of the search system. 12. The method of claim 11 wherein the refining includes: determining a quantity of results related to each recognition hypothesis, and discarding recognition hypotheses having no results. 13. The method of claim 11 wherein the refining includes: determining a quantity of results related to each recognition hypothesis, and adjusting the weight associated with the recognition hypothesis based on the quantity. 14. The method of claim 1 further comprising: detecting compounds in the one or more recognition hypotheses, and wherein the constructing a weighted boolean query includes: constructing the weighted boolean query using the recognition hypotheses and the detected compounds. 15. The method of claim 1 further comprising: detecting compounds in the results of the search system; refining the weighted boolean query based on the detected compounds; providing the refined weighted boolean query to the search system; and providing the new results. 16. A method for generating a search query, comprising: receiving one or more recognition hypotheses, each recognition hypothesis being constructed from a voice search query; determining a length of a shortest recognition hypothesis; pruning a length of each recognition hypothesis up to the length of the shortest recognition hypothesis; determining a length of a longest pruned recognition hypothesis; selecting a number of recognition hypotheses based on the length of the longest pruned recognition hypothesis; determining query term weights; and forming a weighted boolean query out of each term position in the selected recognition hypotheses. 17. The method of claim 16 wherein the pruning includes: removing noise words from the recognition hypotheses. 18. The method of claim 16 wherein the selecting includes: identifying a number of recognition hypotheses based on the determined length of the longest pruned recognition hypothesis, a value representing a total number of terms to be included in a query, and a value representing a proportion of new terms added from a first recognition hypothesis to a second recognition hypothesis. 19. A server comprising: a memory configured to store instructions; and a processor configured to execute the instructions to receive one or more recognition hypothesis, each recognition hypothesis being constructed from a voice search query, determine a length of a shortest recognition hypothesis, prune a length of each recognition hypothesis up to the length of the shortest recognition hypothesis, determine a length of a longest pruned recognition hypothesis, select a number of recognition hypotheses, the number being based on a value representing the length of the longest pruned recognition hypothesis, determine query term weights, and form a weighted boolean query out of each term position in the selected recognition hypotheses. 20. A computer-readable medium containing instructions for controlling at least one processor to perform a method for generating a search query, comprising: receiving at least one recognition hypothesis, the recognition hypothesis being constructed from a voice search query and having one or more terms; determining a length of a shortest recognition hypothesis; pruning a length of each recognition hypothesis up to the length of the shortest recognition hypothesis; determining a length of a longest pruned recognition hypothesis; selecting a number of recognition hypotheses, the number being based on the length of the longest pruned recognition hypothesis; determining term weights; and forming a weighted boolean query out of the selected recognition hypotheses.
