Type to seach and helper text need updating

[Dave Morley]

Bug Description:
The text search box need some love. It currently says "Type to search" which is fine, search for what if I type in a website it fails to find it. The text would be better if it said "Search for an application". The helper text again is too generic "Enter the terms you wish to search for" try something like "To find an application add some words that describe it or the applications name" then there is no mistake as to what it is for.
