search engine on the web -- think of it as Excite Lite. The small
index means WebCrawler is not the place to go when seeking obscure

in response to general searches. WebCrawler opened to the public
on April 20, 1994. It was started as a research project at the
University of Washington. America Online purchased it in March
1995 and was the online service's preferred search engine until

search engine.
