In the course of using these engines in tens of thousands of searches, I have learned much about how they work and what they could and could not find. Each engine has its weaknesses and strengths. All are difficult to learn for the beginner and their particular values only becomes apparent to the experienced and expert user. I created this search engine of search engines to make the difficulties of their use disappear and to enable the novice to take advantage of their intrinsic and sometimes almost hidden power. The search options can easily be changed from the default to another user specific criteria with a few clicks of the mouse.
Some search engines have many more options than others.
In fact, a few have no options at all. Consistent User Interface Most of the powerful search options presented to the user by the various search engines are presented in terms, format, and description that differ significantly from each other, yet still perform the same fundamental operation. This is confusing and daunting as one moves from one engine to the other in the quest for information. In many cases, it is often easier and simpler to just ignore these features and do the simple default search. This means you can focus on your search and not on figuring out what the search engine wants you to do.
