Ok so I am looking for a form/database that can I store around 700,000+ words/phrases.

I want to be able to use a form to paste maybe like 50,000 words/phrases at a time and it would add it to the list of words/phrases removing any duplicate words/phrases

After which I could sort them alphabetically and display just words/phrases that starts with a certain letter.

Does anyone have any Ideas?

Tim...
