Abstract

A first set of search results responsive to a first query during a search session is identified. A snippet is identified for each search result related to the first query. The snippet can be selected based on the location the search tokens from the query in the search result. A second set of search results responsive to a second query during a search session is identified. Repetitive search results can be identified. A second snippet for the repetitive search result is identified. The second snippet can be selected based on the location of the second search tokens in the repetitive search result and the content of the first snippet.

Claims

1. A computer implemented method for generating search result snippets, comprising:

identifying a first set of search results responsive to a first query during a search session, the first query including one or more first search tokens;

for each search result in the first set of search results, identifying a first snippet in content referred to by the search result, the first snippet selected based on a location of the one or more first search tokens of the first query in the content referred to by the search result;

identifying a second set of search results responsive to a different second query during the search session, the second query including one or more second search tokens;

identifying a repetitive search result that is a search result for both the first query and the second query during the search session, wherein the repetitive search result was not selected in the first set of search results; and

selecting a second snippet from a plurality of different snippets in content referred to by the repetitive search result wherein the second snippet is different from the identified first snippet for the repetitive search result, and wherein the second snippet is selected based at least partly on an associated weight that is determined from a location of the second snippet in content referred to by the repetitive search result.

2. The method of claim 1, wherein at least one of the second search tokens from the second query is different from one of the first search tokens from the first query.

3. The method of claim 1, wherein the first snippet is an area of text in the content referred to by the repetitive search result surrounding the one or more first search tokens.

4. The method of claim 1;

wherein the associated weight is also based on a number of the second search tokens that occur in the second snippet.

14. The method of claim 1, further comprising providing the second snippet with the repetitive search result to a client.

5. A machine-readable storage device including a program product having stored instructions executable by data processing apparatus to cause the data processing apparatus to perform operations comprising:

identifying a first set of search results responsive to a first query during a search session, the first query including one or more first search tokens;

for each search result in the first set of search results, identifying a first snippet in content referred to by the search result, the first snippet selected based on a location of the one or more first search tokens of the first query in the content referred to by the search result;

identifying a second set of search results responsive to a different second query during the search session, the second query including one or more second search tokens;

identifying a repetitive search result that is a search result in both the first set of search results and the second set of search results, wherein the repetitive search result was not selected in the first set of search results; and

selecting a second snippet from a plurality of different snippets in content referred to by the repetitive search result wherein the second snippet is different from the identified first snippet for the repetitive search result, and wherein the second snippet is selected based at least partly on an associated weight that is determined from a location of the second snippet in content referred to by the repetitive search result.

6. The machine-readable storage device of claim 5 wherein at least one of the second search tokens from the second query is different from at every one of the first search tokens from the first query.

7. The machine-readable storage device of claim 5 wherein the first snippet is an area of text in the content referred to by the repetitive search result surrounding the one or more first search tokens.

13. The machine-readable storage device of claim 5 wherein the associated weight is also based on a number of the second search tokens that occur in the second snippet.

15. The machine-readable storage device of claim 5, wherein the operations further comprise providing the second snippet with the repetitive search result to a client.

8. A system comprising:

a machine-readable storage device storing a program product; and

a data processing apparatus configured to execute the program product to perform operations comprising;

identifying a first set of search results responsive to a first query during a search session, the first query including one or more first search tokens;

for each search result in the first set of search results, identifying a first snippet in content referred to by the search result, the first snippet selected based on a location of the one or more first search tokens of the first query in the content referred to by the search result;

identifying a second set of search results responsive to a different second query during the search session, the second query including one or more second search tokens;

identifying a repetitive search result that is a search result in both the first set of search results and the second set of search results, wherein the repetitive search result was not selected in the first set of search results; and

selecting a second snippet from a plurality of different snippets in content referred to by the repetitive search result wherein the second snippet is different from the identified first snippet for the repetitive search result, and wherein the second snippet is selected based at least partly on an associated weight that is determined from a location of the second snippet in content referred to by the repetitive search result.

9. The system of claim 8, wherein at least one of the second search tokens from the second query is different from every one of the first search tokens from the first query.

10. The system of claim 8, wherein identifying a repetitive search result comprises identifying a repetitive search result that is a search result in both the first set of search results and the second set of search results where the repetitive search result was selected in the first set of search results.

11. The system of claim 8, wherein the first snippet is an area of text the content referred to by the repetitive search result surrounding the one or more first search tokens.

12. The system of claim 8 wherein the associated weight is also based on a number of the second search tokens that occur in the second snippet.

16. The system of claim 8, wherein the operations further comprise providing the second snippet with the repetitive search result to a client.
