Optional: Some hints concerning search engines:

If you are building a search engine for your class project, have a look at these pages:

  • CLICK ON "advanced" on this page
  • Excite advanced search
  • Yahoo advanced search

    You probably won't have as many options as the IUB search engine but I would expect everybody to implement at least two options (such as Boolean "AND" and "OR" or two search categories). Check out how the first two in the list implement Boolean searches without using the terms "AND" and "OR". Whatever options you choose to implement, they must be well explained to the user.
