Note: We've changed the scope of this ticket - the original information is below in italics.
Display on the portal page the larger, more prominent search text box with a blue button next to it with a magnifying glass icon in it.
I noticed we are introducing an english label within the Search button.
Determine whether we should display the label "Search" in english.
Or only show the search icon?
Or i18n the label? (but comes the issue of getting all those labels, and I'd rather avoid it actually /@JGirault)
