Abstract

Determining a relevancy ranking score is disclosed. A query is received that includes one or more constraints. One of the one or more constraints includes an operator. A search result based on the query is received. The relevancy ranking score for the received search result is determined based at least in part on the operator associated with the one or more constraints of the query.

Claims

1. A system for determining a relevancy ranking score, comprising:

a processor; and

a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to;

receive a query including one or more constraints, wherein one of the one or more constraints includes an operator;

receive a search result based on the query; and

determine the relevancy ranking score for the received search result based at least in part on the operator associated with the one or more constraints of the query.

2. A system as in claim 1, wherein the operator is one of a plurality of operators associated with a query.

3. A system as in claim 1, wherein the operator comprises a CONTAINS operator.

4. A system as in claim 1, wherein the operator comprises a DOES_NOT_CONTAIN is operator.

5. A system as in claim 1, wherein the operator comprises a BEGINS_WITH operator.

6. A system as in claim 1, wherein the operator comprises an ENDS_WITH operator.

7. A system as in claim 1, wherein the operator comprises an ALWAYS_WITHIN operator.

8. A system as in claim 1, wherein the operator comprises an EQUALS operator.

9. A system as in claim 1, wherein the operator comprises a NOT_EQUALS operator.

10. A system as in claim 1, wherein the operator comprises a GREATER_THAN operator.

11. A system as in claim 1, wherein the operator comprises a LESS_THAN operator.

12. A system as in claim 1, wherein the operator comprises an AND operator.

13. A system as in claim 1, wherein the operator comprises an OR operator.

14. A system as in claim 1, wherein the operator comprises a NOT operator.

15. A system as in claim 1, wherein the search result is one of a plurality of search results and wherein the plurality of search results are from a plurality of search sources.

16. A system as in claim 1, wherein the search result includes a ranking from a search source.

17. A system as in claim 1, wherein the processor is further configured to calculate a relevancy ranking based at least in part on the relevancy ranking score for a plurality of search results resulting from the search query.

18. A system as in claim 1, wherein the processor is further configured to calculate a relevancy ranking based at least in part on the relevancy ranking score and based at least in part on a second ranking score for a plurality of search results resulting from the search query.

19. A computer program product for determining a relevancy ranking score, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

receiving a query including one or more constraints, wherein one of the one or more constraints includes an operator;

receiving a search result based on the query; and

determining the relevancy ranking score for the received search result based at least in is part on the operator associated with the one or more constraints of the query.

20. A method of determining a relevancy ranking score, comprising:

receiving a query including one or more constraints, wherein one of the one or more constraints includes an operator;

receiving a search result based on the query; and

determining the relevancy ranking score for the received search result based at least in part on the operator associated with the one or more constraints of the query.
