Abstract

Various embodiments provide for use of multiple different search engines. The individual search engines are configured to conduct searches in different ways across a search space that includes different types of data sets. In at least some embodiments, the type of search engine that is utilized is selected to due characteristics of the data set(s) that is (are) to be searched. In search spaces that include different types of data sets, combining and mixing different search engines to collectively search the search space can provide a desirably fast and robust user experience.

Claims

1. A computer-implemented method for efficient searching of multiple data sets, the method implemented on a computing device by a processor configured to execute instructions that, when executed by the processor, direct the computing device to perform acts comprising:

receiving a search input directed to a search space;

selecting a first search engine configured to conduct a first type of search in the search space across programs and web-related items;

selecting a second search engine configured to conduct a second type of search in the search space across files and communications;

using the first search engine to conduct a search of the programs and web-related items and the second search engine to conduct a search of the files and communications; and

causing a display of results of the search conducted by the first search engine and results of the search conducted by the second search engine.

2. The method of claim 1, wherein search input comprises a search input received via a search box provided as part of a start menu user interface.

3. The method of claim 1, wherein the search space comprises one or more computing devices, one or more servers, or one or more networked data repositories.

4. The method of claim 1, wherein the first type of search comprises a linear search that linearly searches a collection of items in the multiple data sets and the second type of search comprises an index search that searches an index which indexes content in the multiple data sets.

5. The method of claim 1, wherein using the first search engine and using the second search engine occurs at the same time.

6. The method of claim 1, wherein causing the display of results comprises causing a display of results in accordance with pre-defined categories such that results of the search sharing a one of the pre-defined categories are grouped together in a display of results of the search.

7. The method of claim 6, wherein the pre-defined categories or groups comprise programs, web-related items, files, and communications.

8. The method of claim 1, wherein causing the display of results comprises causing a display of results on a letter-by-letter basis as individual letters of the search input are received.

9. A computing device, comprising:

one or more processors; and

a computer-readable medium comprising computer-readable instructions which, when executed, implement acts comprising

receiving a search input;

selecting a first search engine configured to conduct a linear search in a search space across a first one or more data sets;

selecting a second search engine configured to conduct an index search in the search space across a second one or more data sets different from the first one or more data sets; and

using the first search engine to conduct a linear search of the first one or more data sets and using the second search engine to conduct an index search of an index which indexes content in the second one or more data sets.

10. The computing device of claim 9, wherein the first one or more data sets comprise programs loaded on a computing device, applications in a path, control panels, web pages in a favorites folder, or web pages from a browsing history.

11. The computing device of claim 9, wherein second one or more data sets comprise document files, music files, other files, email messages, instant messaging messages, appointments, or contacts.

12. The computing device of claim 9, wherein the acts further comprise causing a display of search results deriving from the linear search and the index search.

13. The computing device of claim 12, wherein the causing the display of search results comprises causing a display of search results grouped together in accordance with pre-defined categories comprising programs, web-related items, files, and communications.

14. The computing device of claim 9, wherein the search input comprises search input received via a search box provided as part of a start menu user interface.

15. The computing device of claim 9, wherein the search space comprises one or more computing devices, one or more servers, or one or more networked data repositories.

16. The computing device of claim 9, wherein using the first search engine and using the second search engine occurs at the same time.

17. A computer-implemented method implemented on a computing device by a processor configured to execute instructions that, when executed by the processor, direct the computing device to perform acts comprising:

receiving a query string entered letter-by-letter as search input;

responsive to determining that the query string is less than a threshold number of letters, using a first search engine to search programs, web-related items, or both, for the letter or letters of the query string as each letter of the query string is entered;

responsive to determining that a number of letters in the query string is equal or greater than the threshold number of letters, repeating the using of the first search engine and also using a second search engine to search files, communications, or both for the query string; and

causing a display of search results on a letter-by-letter basis.

18. The method of claim 17, wherein the first search engine and the second search engine search the query string against a search space containing at least one of programs or web-related items and at least one of files or communications.

19. The method of claim 17, wherein the threshold number of letters is two or three.

20. The method of claim 17, wherein the first search engine is configured to conduct a linear search and the second search engine is configured to conduct an index search.
