Search Engines
Delisting
When pages are removed from a search
engines index. This may happen because
they have been banned or for other reasons,
such as an accidental glitch on the
search engine's part.

Excites fortunes have dropped considerably
since being purchase by @Home. Excite
claims a database of 200+ million pages.
Excite recently lost its top service
spot on Netscapes Netcenter and AOL's
Netfind. These losses have cut Excites
traffic in half.
GoTo
A search engine that sells keywords
via auctions. Goto has gained in popularity
with Webmasters in 1999. Webmasters
can bid on keywords. When a user searches
Goto and clicks on a search result.
Index
The collection of information a search
engine has that searchers can query
against. With crawler-based search engines,
the index is typically copies of all
the web pages they have found from crawling
the web. With human-powered directories,
the index contains the summaries of
all web sites that have been categorized.
Indexer
When a search engine spiders (downloads)
a page on a web, it must process the
page to store it. A spider is responsible
for the downloading, while the Indexer
is responsible for process the page.
An search engine indexer will typically
process a page by removing all HTML
tags, checking for and story links,
often compressing the page by pulling
out filter words, looking for stop words,
and finally storing the page in a online
searchable database.
