Everflux : Once a month
Google updates its entire index of web
sites. That is called the Google Dance
and can last for a couple days - usually
it's from about the 20th to the 28th of
every month. Around June/July 2002 we
started seeing something else through.
Google. results started changing all
through the month, in between the major
updates. This continuous change became
known as everflux. It happens because
Google, in an ongoing effort to make
their results as relevant as possible,
has introduced a "fresh crawl" that runs
each day. The idea behind the fresh
crawl is to update pages that change
regularly. This allows Google to serve
results that are up-to-date with current
events.
Excite : A major search
engine.
Exact Match :
If
not for partial matching, fuzzy
matching, collaborative filtering and
stemming, search engines would only
return exact matches. A search for
"power" would only return documents
containing the exact term, not documents
containing variations or related terms
like powerful, strength, etc...

(same-topic) documents. Some search
engines only consider links from expert

in the collection - when determining
link popularity.

within a search engine index. An expert
index consists only of documents that
are considered expert documents.

Eye Candy
: Aesthetically pleasing web sites are
said to provide eye-candy. The term is
used to describe sites both positively
and negatively. In the context of search
engines and SEO, eye candy is generally
perceived as unnecessary, not
contributing to the marketing effort.
