Hello,
I'm starting a new thread to make sure everybody who is interested
notices it ;-)
You all know that we get quite some complaints (and/or complain ourself)
about our wiki search because "it doesn't find the stuff".
This is mostly caused by the fact that by default the search only lists
pages in the main and Portal namespace.
I propose to change the wiki search and the config of Lucene (the search
engine used in the openSUSE wikis) to
- search all (relevant) namespaces
- use [Namespace-Boost] in lsearch-global.conf to boost the namespaces
that we currently search (main and portal)
The result will be that pages from main and portal namespace will still
be the top-rated search results, with the (currently hidden) results
from other namespaces below.
Here's a list of the namespaces we use, together with the boost value I
propose (1 means top rating, 0.0001 means it will be the last search
result, - means not to include this namespace in the default search [1])
Boost Namespace number/name
1 0 Main
0.0005 1 Talk
0.005 2 User
0.001 3 User talk
0.6 4 Project ("openSUSE")
0.0005 5 Project talk
0.02 6 File
0.0005 7 File talk
0.005 8 MediaWiki
- 9 MediaWiki talk
0.0005 10 Template
- 11 Template talk
0.01 12 Help
0.0005 13 Help talk
0.02 14 Category
0.0005 15 Category talk
0.6 100 SDB
0.0005 101 SDB talk
1 102 Portal
0.0005 103 Portal talk
0.2 104 Archive
0.0005 105 Archive talk
0.2 106 HCL
0.0005 107 HCL talk
- 110 Book
- 111 Book talk
- 122 Property
- 123 Property talk
- 126 Form
- 127 Form talk
- 128 Concept
- 129 Concept talk
- 420 Layer
- 421 Layer talk
Just in case you wonder about the numbers - they are based on what
Wikipedia uses AFAIK:
(0, 1) (1, 0.0005) (2, 0.005) (3, 0.001) (4, 0.01), (6, 0.02),
(8, 0.005), (10, 0.0005), (12, 0.01), (14, 0.02)
and adjusted to our needs (see for example the difference in the project
namespace)
I'd like to know
- if you like this proposal in general,
- if you agree with the list of namespaces to search by default,
- if we want to include the talk pages in the default search and
- if you agree with the boost value for each namespace
In the meantime, I'll fetch some cable ties to tie up Henne - I'm sure
he won't like the idea of including all those namespaces in the default
search ;-))
Needless to say that we might need to finetune the boost values of some
namespaces later (needs some testing with the real wiki content), but in
general I think the above values will work much better than what we have
now ;-)
Regards,
Christian Boltz
[1] Nevertheless, we should set those namespaces to a boost value of
0.0001 in case someone includes them in the search

Wiki search does not work too often, so it would be nice to have
already configured Google search as default:
http://en.opensuse.org/MediaWiki:GoogleSearch
- It is proprietary
+ Google has whole a lot of people taking care of search engine
improvements
+ It is much better guessing what user wants, ie. fuzzy search
+ It doesn't need restart after some update
Try this and check how relevant are results for "wiki":

What is your opinion?
