Welcome to the Wumpus Search Engine!

 
















 
Wumpus is an information retrieval system developed at the University of Waterloo. Its main purpose is to study issues that arise in the context of indexing dynamic text collections in multi-user environments. One particular scenario that we are studying is file system search (aka "desktop search"), in which the underlying text collection is very dynamic and the number of expected index update operations is much greater than the number of search queries submitted by the users of the system.

The intended use of Wumpus is two-fold. It can be used Wumpus is very scalable and has been used on text collections consisting of many hundreds of gigabytes of text and containing dozens of millions of documents. For more information, please have a look at the documentation, the tutorial, or the list of publications.

If you are interested in Linux file system notification necessary for real-time file system indexing, you may find some interesting information on the fschange page. fschange is a patch for the Linux kernel that can be used by a process with superuser rights to keep track of all changes to the file system (recursive watch). Wumpus uses fschange to keep its internal index structures up-to-date.

If you have any questions regarding the Wumpus system, please send an e-mail to: stefan at wumpus-search dot org.

Also, if you would like to use Wumpus as part of your own system, but for some reason are unhappy with the terms of the GPL, please drop me a line, and we can discuss things.
