How does LOREnet work?
To search LOREnet we have developed a search interface that you can use both in this portal and in various VLE environments. It is called LUZI, short for the Dutch for LOREnet Universal Search Interface. This page tells you about LUZI and how to use it.

Technology

LUZI is an expansion on DAREnet's search interface. It uses the Meresco search engine based on Lucene. The following architectural diagram describes the positioning and use of LUZI.

Based on the Requirementsdocument written by John May.

LUZI functions as a plug-in for both the portal and the VLEs. Search questions are translated into SOAP-XML messages that are sent to Meresco's search engine. Search results are then translated into an HTML message. For this the VLEs need to have a page on their own screen. See below for an explanation.

Use of LUZI in a VLE

The LUZI page must be included on a VLE page. This is http://lorenet.org/luzi. This page shows the search box and results produced by the search.

Conditions
  • The included page must communicate all query arguments to the LUZI page (See example)
  • To import an object, there is a call to a JavaScript method importLink( <aUrl> ). Your VLE must define this so you can call up your own import function.
  • Include the style sheet http://lorenet.org/css/luzi.css using a link at the head of the page. Your VLE can of course modify the style sheet. Just choose the relevant points of style and override them. Then include the second style sheet as your own. The most recently defined style is used for an element.

Examples

Example of a code to include LUZI on PHP page: 

<?php
include "http://lorenet.nl/luzi?".$_SERVER['QUERY_STRING']
?>
