If you use Google Docs or Mail or store your files in Dropbox, you should be aware of Greplin. It enables you to search your mail and documents stored in the cloud (here’s my previous post about it). Greplin recently announced that it was now indexing full content stored in Dropbox. Before this, a search in Greplin would return just documents whose titles matched your search query. Now the results will be based on an index of the full text of your documents.
As before, Greplin is a personal tool. Although you can access it from anywhere you have an Internet connection, you log in to your account to search across your other cloud services. No-one else can search Greplin and see your information.
