Content storage and collaboration solution, Box.net, has really been on a tear with new and enhanced features. In the last two months, the service has launched enhanced collaboration tools and a web-based word processor; today, they add another new feature: full-text search!

Now, Box.net Business customers can search the full text of PDF, TXT, CSV, Microsoft Word, PowerPoint and Excel files and Box Web Documents. The new search feature will also scan any file descriptions added by users, which is great for more generic documents that might be tagged for something more specific. According to Box, they've already tested the new search feature with one customer who has more than 300,000 documents, and the results have been great.

When I talked to Box last month, it was clear that the company's focus is really on building tools for small and large businesses. Having used Box to share and collaborate with some of my fellow Weblogs bloggers, that focus really comes through in the actual service itself.

With full-text search, Box is really making the argument for businesses to move their file systems online or over to Box, without having to pay for something like Microsoft SharePoint. And because you can access the documents from anywhere, this is a really nice solution for telecommuting employees or businesses with multiple locations.
