Yahoo buys e-mail search company

Google, Microsoft, Yahoo - the battle of the giants in search technology, online advertising and community building is ongoing.

Google opened the front with their huge and searchable e-mail accounts, followed by search technology that allows to search your desktop. In addition and in between, they relaunched book searches.

Yahoo so far countered every move - increased the size of their inbox, made their emails searchable (via Oddpost). This tool now got improved when Yahoo bought Stata Labs that sells an e-mail application called Bloomba that lets people search message text and attachments.

Microsoft also has designs to integrate desktop, e-mail and Web search from the operating system, and toward that end it recently bought a small e-mail search company called Lookup.

Where is Amazon's A9? They will be there soon as well, we bet.
