Abstract

A method and apparatus for using network traffic logs for search enhancement is disclosed. According to one embodiment, network usage is tracked by generating log files. These log files among other things indicate the frequency web pages are referenced and modified. These log files or information from these log files can then be used to improve document ranking, improve web crawling, determine tiers in a multi-tiered index, determine where to insert a document in a multi-tiered index, determine link weights, and update a search engine index.

Claims

1. A method of placing a document in a multi-tiered index, comprising the steps of:

monitoring, over a period of time, requests for documents made by users;

wherein said requests are intercepted by a device on a network that is remote relatively to a location of said multi-tiered index;

determining which tier of said multi-tiered index to place said document based at least in part on a frequency that said users have requested said document; and

placing said document in said tier.

2. The method of claim 1, wherein the step of monitoring further includes generating usage logs that identify said frequency and the step of determining further includes determining which tier of said multi-tiered index to place said document based at least in part on said usage logs.

3. The method of claim 1, wherein the step of placing said document in said tier includes removing said document from a relatively lower tier and placing said document in a relatively higher tier in response to said document being requested with a relatively higher frequency than other documents in said lower tier.

4. A computer-readable medium carrying one or more sequences of instructions for placing a document in a multi-tiered index, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

monitoring, over a period of time, requests for documents made by users;

wherein said requests are intercepted by a device on a network that is remote relatively to a location of said multi-tiered index;

determining which tier of said multi-tiered index to place said document based at least in part on a frequency that said users have requested said document; and

placing said document in said tier.

5. The computer-readable medium of claim 4, wherein the step of monitoring further includes

generating usage logs that identify said frequency and the step of determining further includes determining which tier of said multi-tiered index to place said document based at least in part on said usage logs.

6. The computer-readable medium of claim 4, wherein the step of placing said document in said tier includes removing said document from a relatively lower tier and placing said document in a relatively higher tier in response to said document being requested with a relatively higher frequency than other documents in said lower tier.
