I found a very little contradiction between what is written on the web 101 page and the material that is in the assignment. the web 101 page says a search engine is a webserver and the assignment says it is a website.
Not sure if I should post this here, or if it is relevant, but I thought that this may be confusing to starters and it would help get the site even more flawless.
Technically the search engine website sends the data to the search engine server then searches it’s database for the collection of websites that match the query. They both are partially correct
