comment Custom search engine
Thank you. I have no idea about how should I build that application. How long should it take until I will be able to search myapplication(where the results are links, like in every other search engine)? (I know that I a pushing it too far, but I really need an estimation in order to make a decision.)

comment Indexing a database
What I meant was, If I have separate indexes on School and ClssYear, would they be useful when searching for all people who went to Duke from classes between 1980 and 1984?

But would in your example two indexes: one on School and the other one on ClassYear be useful in any of the cases?

While reading your answer, another question popped into my mind: Are Primary Keys usually automatically indexed, or do I have to specify myself that they will be indexed? Say, for example, in a MySQL database?

It is a purely theoretical question("what if/why not").
