in thread Writing a database lookup tool
Please clearly mark updates to your posts. I suggest you actually take the time to try this out for yourself, the learning experience will be worth while and you'll soon relise how vague your questions actually are, and how essentially meaningless it would be to give you a result of a query running on X million records within my tuned environment for a database platform you'll never use.
Your concept of server and offline is flawed. Your laptop would be the server in that it would host the database, webserver, Solr instance or whatever.
Update: consider someone asking a piano maker "I have no experience in building a piano, no knowledge of wood and little knowledge of metal work. Roughly how long will it me take to build a piano by hand?"
Update: fixed typo.
