Friends, don't you find any problem with the algorithm used to search in the software center. Giving you an example:

Let us search for MultiGet. When I write "Mult" in the search MultiGet appears at the 6th position. As soon as I add 'i', I see that surprisingly, MultiGet now appears at 10th position with some rather irrelevant options before it.

Not understandable...


I can confirm this. Looks like matches in the app name doesn't score comparatively higher than matches in the descriptions. You should file a bug on Launchpad if there isn't already one...

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,
Mikkel
