Thread:Extension talk:Zend Search Lucene for MediaWiki/How to install it on a localhost of windows

I am a newer for Mediawiki. I use the Mediawiki on my comuputer (windows operation system, PHP is in the directory C:\xampp\, Wiki is in the directory D:\www\htdocs\, SQL is in the directory D\www\mysql\). It's very good, and I want to find a search engine. I think this extension is very good. During the process of installation, I have some questions as following:

1 In the frist step, I have downloaded the Zend framwork. I put the contents in \htdocs\psl-suche\. Is it right? is there some paths to be added or changed?

2 In the second step, I move the file PslZendSearchLuceneIndexer.php to \htdocs\psl-suche\. How can I "Edit the marked parts of this file as descriped in it." ?

Thanks a lot!
