Unlike Nokia, there is no in-device search utility from Sony Ericsson to search the local contents of a UIQ3 mobile device. Easy Search by Webgate is a mobile search application for UIQ 3 based mobile devices such as Motorola Z8, Sony Ericsson M600, P1, P990, W950 and W960 that allows you to quickly search the following items on your mobile device:

-Messages
-E-mails
-Files
-Contacts
-Appointments
-ToDos
-Events
-Reminders
-Anniversaries

Easy Search searches using keywords:

+ whole words
+ combinations of words
+ sequence of letters

Other features of Easy Search include:

+ Enable or disable case sensitive search
+ Use the search history to return to a previous search by selecting an old entry from a drop-down list.
+ Once the search is started the tab caption displays the current search state: Searching, Finished, or Cancelled.
+ Search results are divided in tabs for each items that you search.
+ Each item you find (files, messages, etc.) can then be opened by the corresponding viewer program on your phone, associated with the item type.
