jetpack-omnisearch

Hello, When attempting to network activate this crashed the server, but we previously had Omnisearch activated on all sites on the Network when it was integrated in Jetpack. Removing the plugin via FTP restored everything to normal. Anybody else have an issue with network activation? Have not tired single site activation yet.

I was looking for some searching tool that could search for all fields (not only title) and would work fine in mobiles. Omnisearch makes it possible in a simply way.
