Choosing the best Search Engine

If you're unsure of which search engine to use, follow this chart -

I have an idea for a broad topic

I want an overview of my topic

Yahoo organizes information in "subject trees" from general to specific topics
I need a small number of relevant hits and an idea of what's in each document before I go to each page Excite hits have excellent summaries.
What's available on the Internet for my topic? Dogpile simultaneously searches 23 different databases - so you'll get a broad range of sites
I don't have a lot of time - so I want quality, evaluated sites that have reviews and ratings. Magellan is a smaller database with descriptive reviews of sites.
I want to do a simple, straightforward search of a word or phrase. Lycos is a good choice for such a search
I need to do a pinpoint search because my terms are narrow. Alta Vista is the largest of the Web databases, and is a fast indexer of full text.
I have common keywords that probably appear in many documents and should make my search specific. HotBot offers lots of options for searching, with ranked results
I'm looking for a phrase or string of words Open Text is a good place to find a phrase, quotation, etc.
I want to browse Yahoo with its subject trees, is always a good place to browse.
I need balanced information from verified sources that I can take home with me Go to the library card catalog!
