Microsoft will no longer offer Linux or Unix versions of its enterprise search products after a wave of releases set to ship in the first half of this year, the company announced in an official blog post Thursday. After Microsoft bought Fast Search & Transfer in 2008, it said it would continue offering and updating standalone versions of the company's ESP platform for Linux and Unix, wrote Bjorn Olstad, CTO for Fast and a Microsoft distinguished engineer. "Over the last two years, we’ve done just that." But the products being released this year will be the last containing a search core compatible with Linux and Unix, he said.
