everflux
Once a month Google
updates its entire index of web sites. That
is called the Google Dance and can
last for a couple of days – usually it’s from about the 20th
to the 28th of every month. Around June/July 2002 we started seeing
something else though. 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.

exact match

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.
expert document

documents. Some search engines only

the collection - when determining link
popularity. According to the Hilltop

the specific purpose of directing people towards resources".
