Improved search engine for DokuWiki, based on Sphinx Search.
You can find the latest version of this plugin at:
https://github.com/abiliojr/bettersearch
This is yet another attempt at trying to improve DokuWiki search results.
Features:
- Ranks the results based on several factors:
- Number of views.
- Number of edits.
- Number of references from other articles.
- Number of clicks from previous searches.
- Freshness of the article.
- Uses Sphinx, an efficient engine that is used by big ones, like Craigslist, to find needles in huge haystacks.
- Better text matches, specially useful with non-English languages.
This plugin requires a Sphinx Search server up and running.
Sphinx supports English, German and Russian out of the box. In case your wiki is using a different language, be sure Sphinx was compiled with libstemmer. Check http://sphinxsearch.com/docs/latest/conf-morphology.html for more information.
Please check settings.php and use the provided sphinx.conf as a reference to edit your sphinx configuration.
If you're installing this on an existing wiki, copying a lot of files directly into the wiki data directory, or any reason that needs a reindexing, please run:
php reindex.php
The basic usage is self explanatory. The plugin includes the following sintax:
In the text field, include the namespace preceeded by ns: For example,
the next line will restrict the search within the root namespace:
this is the search phrase ns:root
This is a departure from the original DokuWiki's @ sign convention, but the change was needed to include full compatibility with Sphinx's advanced syntax capabilities (see next section).
The plugin supports the Sphinx's extended query syntax. For more information please visit: http://sphinxsearch.com/docs/latest/extended-syntax.html
The ranking formula is still considered experimental. The weights for each factor were determined using AHP (Analytic hierarchy process). See extras/ahp.php for more information.
Ideas, suggestions, bug reports and help (specially on the ranker formula and settings) are welcomed! Please go to:

And contact me through the issues section.
If you install this plugin manually, make sure it is installed in lib/plugins/bettersearch/ - if the directory is called different it will not work!
