- if you agree with the boost value for each namespace
The number system you mentioned above is a little to cryptical for me. "Say" what is first, second and so on in the result list.
Well, it depends on how good the page matches the search term ;-)
Think of the boost value as a "weight" (not as a "first", "second", ...) that is part of the ranking calculation. The other part in the calculation is how good the page content matches the search term.
Let me give you an example:
Search for "download openSUSE distribution" [1]
Let's assume there are two pages with a 100% text match: - /Download - /Archive:Download_12.2
Both search results are equal, now the boost value comes into play, and you'll get the following search result order: - /Download: 100% match * 1 = 100 "points" - /Release_Notes: 70% match * 1 = 70 "points" - openSUSE:Download_statistics: 80% match * 0.6 = 48 "points" - /Archive:Download_12.2: 100% match * 0.2 = 20 "points"
So in the end /Download is the first search result (100 "points"), followed by some other pages (which contain only two of the three words you searched) and, much more downwards, /Archive:Download_12.2
The result can also be the other way round - a 100% match in the SDB namespace (= 60 "points") can be the top result if there's only a 50% match in the main namespace (= 50 "points").
Nevertheless, it will be quite rare that a page in the Talk namespace ends up as first search result because it can get a maximum of 100% match * 0.0005 = 0.05 "points".
Does this explain the boost values?

[1] I just invented this search and its results, which means the "real" search will most probably give you different results and/or different page content.
