Its the local search application that comes straight from Nokia probably extracted from the Nokia E50.

Such an application is just must have and it seams that one of my dreams comes true, application allows you to quickly search in messages, email, calendar, contacts and other files with any keyword you want.
You can define in which specific categories of the mobile the search should be processed to get your results as fast as possible.

After the search, you 'll get a list with all found results separated into categories and you can also switch to the associated application, for example you can jump directly to the founded entry in the contacts application.
