Chapter 3

  From chapter 3 I have discovered many interesting features of a web browser search engine. First, when I search for something on a web browser, I have always thought that I searched the world wide web to find the results. I learned that the search engine only searches its own database for information that its bots (spiders) have previously collected. Also, the book mentioned that webpage creators can submit their URLs to the search engine database. This I found a useful feature, because with the vast amount of content available out there, it would be really difficult for webpage creators to take a stand on the web browsers.

   I have also learned about natural language query and logical operators that can be used in the search engine. At the end, databases do not understand natural language; that is why search engines use a process called “parsing” to convert a natural language query into a logical query. However, if you want to narrow down your search even further, you can include logical operators into your natural language query. This can be done by adding “AND”, “OR”, or “NOT”. Usually not entered in the search bar as a minus (-) sign in the search. One example could be (jaguar –car); this would include all the information about jaguars that are not related to cars in any way.
