Google search appliance could be the way to go on a small scale, and most likely temporary, solution.

The real questions are:

How valuable are your documents ?
How much money do they generate ?
What is the cost for not being able to locate a document ?
What kind of processes are these documents used in ?
How distributed is your user base ?
How close to the your business core are these documents.

You certainly need a document management solution (or ECM), which one will depend basically on the answers to the previous questions.
