Looking more into this I realise what the real problem is. The problem 
lies in applications which contain the term "multi" as a single token. 
Fx. applications which incorrectly spells "multimedia" as "multi-media". 
This latter form becomes indexed as two words "multi" and "media". This 
gives and exact match on the word "multi" when searching and this ranks 
higher than a prefix-match on words such as "MultiGet".
Academics aside - the fix is still to make sure that any form of match 
in the app title scores higher than matches in the description.
Cheers,
