An "and" filter. Okay.

One way to do it, written in php:
<?php

$build_filter = "";
$num_of_AND = 0;

if ($sn){
    $build_filter  ="(sn=*". $sn ."*)";
    $num_of_AND++;
    }

if ($gn){
    $build_filter  ="(givename=*". $sn ."*)";
    $num_of_AND++;
    }

if ($user){
    $build_filter  ="(uid=*". $user ."*)";
    $num_of_AND++;
    }

if ($num_of_AND > 1){
    $filter_for_search = "(&" . $build_filter . ")";
    } else {    \\ if there is only one search term
    $filter_for_search = $build_filter;
    }
?>

This way, you can have one AND(OR), or thirty, and change the |
or the & when you are ready building the whole string.
