Elgg, is an open source social network engine providing out-of-the box functionality for deploying social-aware applications in education, business, non-profit and other environments.

Elgg runs on Apache, PHP and MySQL — the same open source platform that the majority of web applications are written in. Elgg is compatible with enterprise technologies like the Zend Platform and any server environment that can run the Apache web server.

Completely re-writen from scratch, Elgg 1.0 is lightweight, extensible, and easily customizable. The vibrant community of developers is producing new mods and themes that extend and expands the capabilities of the platform.

Presentation by Geoff Livingston.

Livingston asserts:

I just wonder if most companies will ever get it, that organizational social media really is about peering with their customers, partners and employees, rather than broadcasting a cleverly disguised ad or white paper in the form “user generated content” or a “blog post.”

The mod

Off-the-shelf, Sphider only returns one portion of a document in which the searched keyword is found. With this mod, Sphider will display as many as 5 portions of a document instead:

replace lines 564 to 572 in searchfunctions.php:

$begin_pos = max(0, $places[$begin] - 30);
$fulltxt = substr($fulltxt, $begin_pos, $desc_length);
if ($places[$begin] > 0) {
	$begin_pos = strpos($fulltxt, " ");
}
$fulltxt = substr($fulltxt, $begin_pos, $desc_length);
$fulltxt = substr($fulltxt, 0, strrpos($fulltxt, " "))  ;
$fulltxt = $fulltxt;

}

with this:

$tempfulltxt ="";
$begin_pos = max(0, $places[$begin] - 30);
$tempfulltxt = substr($fulltxt, $begin_pos, $desc_length);

if ($places[$begin] > 0) {
