Yitzchak, are you interested in actually searching the fulltext? Or just highlighting the terms? If you're only interested in highlighting it, it might be a whole lot easier to implement this in javascript through something like jQuery: http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html That way you're not juggling mostly redundant Lucene indexes and trying to keep them synced. How are you getting your search results? Does Greenstone have some sort of search API that returns the highlighted results? Would it make a difference if you could add a field to the Lucene document (meaning would you have access to it through your PHP API to Greenstone)? If so, you could probably do this pretty easily via one of the JVM scripting languages (Groovy, JRuby, Jython, Quercus -- PHP in the JVM) so you just have the single Lucene index instead of multiple. Another approach might be to serve the Lucene index via Solr [1] or Lucene-WS (http://lucene-ws.net/) which would allow you to skip Greenstone altogether for searching. Basically, I would try to avoid going the Zend_Lucene route if at all possible. -Ross. 1. http://www.google.com/search?q=solr+on+an+existing+lucene+index&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a On Tue, Sep 29, 2009 at 11:32 AM, Yitzchak Schaffer < [log in to unmask]> wrote: > Erik Hatcher wrote: > >> I'm a bit confused then.
