getting text in Search tab

[Marja van Waes <marja11@xs4all.nl>]

Hi all,

In our WebHelp, for many languages the Search tab is as good as 
invisible because there is no text in it, like here:
http://doc.mageia.org/installer/3/ru/content/index.html

For German, the text is in English
http://doc.mageia.org/installer/3/de/content/index.html

For us, only in English and French it is as it should be.

What must I do to get the correct translation of "Search" in that tab?

Kind regards,
Marja
