Abstract

A search system monitors the input of a search query by a user. Before the user finishes entering the search query, the search system identifies and sends a portion of the query as a partial query to the search engine. Based on the partial query, the search engine creates a set of predicted queries. This process may take into account prior queries submitted by a community of users, and may take into account a user profile. The predicted queries are to be sent back to the user for possible selection. The search system may also cache search results corresponding to one or more of the predicted queries in anticipation of the user selecting one of the predicted queries. The search engine may also return at least a portion of the search results corresponding to one or more of the predicted queries.

Claims

1. A computer-implemented method performed at a server system for processing a search query, comprising:

receiving at the server system the search query from a search requestor at a client system that is distinct from the server system;

at the server system, responding to receiving the search query, including;

determining whether the search query is a partial search query or a final search query;

wherein,

when the search query is deemed to be a partial search query;

(A) predicting a plurality of predicted queries based upon the search query, wherein the predicting (A) includes selecting the predicted queries based, at least in part, on how many times each of the predicted queries has been reused from a cache at the server system;

(B) obtaining a first list of documents corresponding to the plurality of predicted queries, wherein the first list of documents is obtained by combining respective documents corresponding to individual predicted queries in the plurality of predicted queries prior to receiving a selection of any predicted query in the plurality of predicted queries from the search requester; and

(C) transmitting, from the server system, (i) the plurality of predicted queries, and (ii) the first list of documents corresponding to the plurality of predicted queries to the search requestor at the client system; and

when the search query is deemed to be a final search query;

(i) obtaining a second list of documents corresponding to the final search query, wherein at least a portion of the list of documents is obtained using a server system cache index and associated cache; and

(ii) transmitting, from the server system, the second list of documents to the search requestor at the client system;

wherein the predicting (A), obtaining (B) and transmitting (C) are executed before obtaining, at the server system, an affirmation, by the search requestor, of a request for executing the search query.

2. The method of claim 1, wherein the predicting (A), obtaining (B) and transmitting (C) are executed before an execution, by the search requestor, of a predicted query in the plurality of predicted queries.

3. The method of claim 1, wherein the search query is deemed to be a partial search query and includes a complete search term.

4. The method of claim 1, wherein the search query is deemed to be a partial search query, the method further comprising:

comparing one or more characters of the search query to entries in a dictionary; and

creating the plurality of predicted queries from one or more of the entries in the dictionary whose entries include the at least one or more characters.

5. The method of claim 4, wherein the plurality of predicted queries is created from entries in the dictionary whose entries begin with the at least one or more characters.

6. The method of claim 4, further comprising:

selecting the dictionary from a plurality of dictionaries.

7. The method of claim 6, further comprising:

selecting the dictionary based on information obtained from a user profile of the search requestor.

8. The method of claim 1, wherein the predicting (A) further includes ordering the predicted queries based, at least in part, on how many times each of the predicted queries has been reused from the cache at the server system.

9. A server system, comprising:

one or more hardware processors;

hardware memory; and

one or more programs stored in the memory for execution by the one or more processors, the one or more programs comprising instructions for;

receiving at the server system a search query from a search requestor at a client system that is distinct from the server system;

at the server system, responding to receiving the search query, including;

determining whether the search query is a partial search query or a final search query;

wherein,

when the search query is deemed to be a partial search query;

(A) predicting a plurality of predicted queries based upon the search query, wherein the instructions for predicting include instructions for selecting the predicted queries based, at least in part, on how many times each of the predicted queries has been reused from a cache at the server system;

(B) obtaining a first list of documents corresponding to the plurality of predicted queries, wherein the first list of documents is obtained by combining respective documents corresponding to individual predicted queries in the plurality of predicted queries prior to receiving a selection of any predicted query in the plurality of predicted queries from the search requester; and

(C) transmitting, from the server system, (i) the plurality of-predicted queries, and (ii) the first list of documents corresponding to the plurality of predicted queries to the search requestor at the client system; and

when the search query is deemed to be a final search query;

(i) obtaining a second list of documents corresponding to the final search query, wherein at least a portion of the list of documents is obtained using a server system cache index and associated cache; and

(i) transmitting, from the server system, the second list of documents to the search requestor at the client system;

wherein the predicting (A), obtaining (B) and transmitting (C) are executed before obtaining, at the server system, an affirmation, by the search requestor, of a request for executing the search query.

10. The server system of claim 9, wherein the predicting (A), obtaining (B) and transmitting (C) are executed before an execution, by the search requestor, of a predicted query in the plurality of predicted queries.

11. The server system of claim 9, wherein the search query includes a complete search term.

12. The server system of claim 9, wherein the search query is deemed to be a partial search query, the one or more programs further comprising instructions for:

comparing one or more characters of the search query to entries in a dictionary; and

creating the plurality of predicted queries from one or more of the entries in the dictionary whose entries include the at least one or more characters.

13. The server system of claim 12, wherein the plurality of predicted queries is created from entries in the dictionary whose entries begin with the at least one or more characters.

14. The server system of claim 12, the one or more programs further comprising instructions for:

selecting the dictionary from a plurality of dictionaries.

15. The server system of claim 14, the one or more programs further comprising instructions for:

selecting the dictionary based on information obtained from a user profile of the search requestor.

16. The server system of claim 9, wherein the instructions for predicting further include instructions for ordering the predicted queries based, at least in part, on how many times each of the predicted queries has been reused from the cache at the server system.

17. A non-transitory computer readable storage medium storing one or more programs configured for execution by a computer, the one or more programs comprising instructions for:

receiving a search query from a search requestor at a client system that is distinct from the server system;

responding to receiving the search query, including;

determining whether the search query is a partial search query or a final search query;

wherein,

when the search query is deemed to be a partial search query;

(A) predicting from the search query a plurality of predicted queries based upon the search query, wherein the instructions for predicting include instructions for selecting the predicted queries based, at least in part, on how many times each of the predicted queries has been reused from a cache at the server system;
