Dear Mr/Miss:
Sorry to interrupt you but there are two problems to ask you
for help. It puzzles us for a long time.
We built a local wiki using mediawiki by downloading the page
articles
fromhttp://download.wikimedia.org/enwiki. However, the data
cannot be imported completely by virtue of the mwdumper.jar and it
stopped halfway saying that there is IllegalArguments. We tried
different source data but no use. Is there something wrong with our
configuration?
It's hard to work correctly with these huge dumps. Try to
download a
different dump. Someone would have better answer than me.
Besides, given a word pair "lion
cat" as the query, the
results returned from the local wiki are differnt from that on the
web.
Wikipedia on the web returned many items for the query
but the local
wiki returned no results. How can make them make return the same
query
results.
Wikipedia uses Lucene search, while
MediaWiki's default install search
is MySQL MyISAM fulltext index - which is much simplier and slower.
You may try to install Lucene
http://www.mediawiki.org/wiki/Lucene
SphinxSearch is somewhat simplier alternative, probably a bit easier to
install - I use it at some wikis.
