[Mediawiki-l] Questions on lucene-search-2.0

I was finally able to install the Lucene search engine using the code from http://svn.wikimedia.org/svnroot/mediawiki/trunk/lucene-search-2.0, but I have some questions regarding updating indexes. Options for the importer are listed as: -n - create a new index (erase the old one if exists) -s - make index snapshot when finished -l limit_num - add at most limit_num articles -o optimize - true/false overrides optimization param from global settings -m mergeFactor - overrides param from global settings -b maxBufDocs - overrides param from global settings --snapshot <db> - make snapshot only for dbname Can anyone suggest an ideal way for updating the indexes? I've setup an hourly cronjob to dump current wiki content, import the dump, and make an index snapshot when finished (-s). Is this preferred over just creating a new index each hour? Thanks in advance, Trey Valenta
