[CALIBK12] [CSLA Research Update] Search engine study

[Lesley Farmer]

Search-engine freshnessThe update strategies of search engines Google,
Yahoo, and MSN/Live.com were analyzed by testing the updates of 40
daily updated pages and 30 irregularly updated pages. It was found that
the search engines change in up-to-dateness over the years and that
none has an ideal solution for index freshness. A major problem is the
delay in making crawled pages available for searching, which differs
from one engine to another.Lewandowski, D. (2008). A three-year study
of the freshness of web search engine databases. Journal of Information
