Why are search engines so different

The Jux2 Meta Search engine which provides results based on the results of google,yahoo and MSN provides a rather surprising statistic showing how much these major search engines differ in the top queries results.

Is it because the indexing method is different for these search engines? Or just a result of the type of use by the users of the searchers! I mean, do some results move up due to that being clicked upon by many users.

The rate of re-indexing will also be different, which can lead to the differences in the results. All this aside, the algorithms used by these engines should be different leading to these differences.

Veronica-a search engine for gopher protocol

The Gopher protocol is now used very rarely if at all. But Veronica was one of the first indexing engines. The latest version known as(Dont click on this link with internet explorer-use firefox or other browsers that support the Gopher protocol) Veronica-2 is still active. It is of interest as it does not index the contents of the files.

If you click on Search Veronica-2, a dialog box will appear where you can provide your query. The list of gopher servers that have the word(s) will be listed.Try using "SRS" as the query. It refers to the the servers with protein and nucleic acid sequences.

The latest addition to the search engines is VISHNU(Search VISHNU (experimental)), it arranges the results based on the folders in which the files are stored. It also shows the number of files in that folder. To begin with the indexing engine should have these basic features. Better features can be added later.
