Abstract

After receiving a first user request including a first set of search keywords, a computer identifies a first set of chunks within multiple documents, wherein each chunk includes terms matching the first set of search keywords, and displays at least a portion of the first set of chunks, including highlighting the terms matching the first set of search keywords in the displayed portion in a first manner. After receiving a second user request to search among the documents for documents that satisfy a second set of search keywords, the computer identifies a second set of chunks within the documents, wherein each chunk includes terms matching the second set of search keywords, and displays at least a portion of the second set of chunks, including highlighting the terms matching the second set of search keywords in the displayed portion in a second manner that is different from the first manner.

Claims

1. A computer-implemented method, comprising:

at a computer having memory, a display, and one or more processors;

displaying the at least one chunk in an order consistent with its relevancy to the first set of search keywords in the first set of chunks; and

displaying the at least one chunk in an order consistent with its relevancy to the second set of search keywords in the second set of chunks.

4. The method of claim 1, wherein the second set of chunks includes at least one chunk that is not included in the first set of chunks.

5. The method of claim 1, wherein the second set of search keywords is different from the first set of search keywords.

6. A computer-implemented method, comprising:

at a computer having memory, a display, and one or more processors;

receiving, from a user, a first user request including a first set of search keywords;

identifying multiple documents, wherein each document includes at least one chunk that satisfies the first set of search keywords;

receiving, from the user, a second user request to search among the chunks in the identified documents for chunks that satisfy a second set of search keywords;

identifying a subset of the chunks, wherein each chunk in the subset satisfies the second set of search keywords; and

displaying, to the user, at least one of the subset of the chunks on the display.

7. The method of claim 6, further comprising:

in response to the first user request, displaying the chunks in the identified documents in accordance with their relevancy to the first set of search keywords; and

in response to the second user request, displaying the subset of chunks in accordance with their relevancy to the second set of search keywords.

8. The method of claim 7, further comprising:

highlighting terms in the subset of chunks matching the first set of search keywords, if any, in a first manner; and

highlighting terms in the subset of chunks matching the second set of search keywords in a second manner that is different from the first manner.

9. The method of claim 6, wherein the subset of chunks includes a first chunk and a second chunk, further comprising:

in response to the first user request, displaying the first chunk ahead of the second chunk; and

in response to the second user request, displaying the second chunk ahead of the first chunk.

10. The method of claim 6, wherein the second set of search keywords is different from the first set of search keywords.

11. A computer system, comprising:

memory;

a display;

one or more processors;

one or more programs stored in the memory and configured for execution by the one or more processors, the one or more programs including;

instructions for receiving a first user request including a first set of search keywords;

instructions for identifying a first set of chunks within multiple documents, wherein each chunk includes terms matching the first set of search keywords;

instructions for displaying at least a portion of the first set of chunks on the display, including highlighting the terms matching the first set of search keywords in the displayed portion in a first manner;

instructions for receiving a second user request to search among the documents for documents that satisfy a second set of search keywords;

instructions for identifying a second set of chunks within the documents, wherein each chunk includes terms matching the second set of search keywords; and

instructions for displaying at least a portion of the second set of chunks on the display, including highlighting the terms matching the second set of search keywords in the displayed portion in a second manner that is different from the first manner.

12. The computer system of claim 11, wherein the second set of chunks includes at least one chunk that is included in the first set of chunks.

13. The computer system of claim 12, further comprising:

instructions for displaying the at least one chunk in an order consistent with its relevancy to the first set of search keywords in the first set of chunks; and

instructions for displaying the at least one chunk in an order consistent with its relevancy to the second set of search keywords in the second set of chunks.

14. The computer system of claim 11, further comprising:

instructions for highlighting terms in the second set of chunks matching the first set of search keywords, if any, in a first manner; and

instructions for highlighting terms in the second set of chunks matching the second set of search keywords in a second manner that is different from the first manner.

15. The computer system of claim 11, wherein both the first set of chunks and the second set of chunks include a first chunk and a second chunk, further comprising:

instructions for displaying the first chunk ahead of the second chunk in response to the first user request; and

instructions for displaying the second chunk ahead of the first chunk in response to the second user request.

16. The computer system of claim 11, wherein the second set of chunks includes at least one chunk that is not included in the first set of chunks.

17. The computer system of claim 11, wherein the second set of search keywords is different from the first set of search keywords.

18. A computer readable storage medium having stored therein instructions, which when executed by a computer system having a display, cause the computer system to:

receive a first user request including a first set of search keywords;

identify a first set of chunks within multiple documents, wherein each chunk includes terms matching the first set of search keywords;
