Installation Steps

Search tier:

Solr with RankingAlgorithm
1. Download and install Apache Solr with RankingAlgorithm – #downloads ( Has the demos, 1m wikipedia and 390k mbartists index)
2. Change to example directory and run start_solr.sh
3. Access from a browser, http://search_ipaddress:8983/solr/wikipedia/select/?q=ac_field:”san+fran”&rows=15&wt=json&indent=true (If this works, your Solr with RankingAlgorithm installation is working properly)
Note: You can edit the schema wikipedia index or the mbartists to make your own. You can access the schema under multicore/wikipedia.

Web tier:

Scripts

1. Copy the example/autocomplete/search_ac.jsp (java web server like tomcat/jetty/glassfish) or example/autocomplete/search_ac.php (apache web server) to your web application document root directory
2. Edit the script and change the searchhost in the URL to your search host ip address or host name or add searchhost in /etc/hosts. Change the core context from “wikipedia” to your context as needed.

Client tier

Scripts

1. Download and install the open source jquery javascript library from http://jquery.com, the version should be at least 1.6.8. You can download the latest version also.
2. Download the autocomplete jquery script from here: http://solr-ra.tgels.org/autocomplete/jquery.autocomplete_solr-ra.js ( You do not have to use this autocomplete script but can use your own or use a jquery plugin, http://docs.jquery.com/UI/Autocomplete)
3. Add the below lines to your html file in the section:

<script src="javascripts/jquery.1.6.8/jquery.js"></script>
<script type='text/javascript' src='javascripts/jquery.autocomplete_solr-ra.js'></script>
<script>
$("#ac1").autocomplete("/search_ac.jsp", 
{ 
	minChars:1, 
	width:350, 
	scroll:true, 
	scrollHeight:200
	});
</script>
<style>

.ac_results {
	padding: 0px;
	border: 1px solid black;
	background-color: white;
	overflow: hidden;
	z-index: 99999;
}

.ac_results ul {
	width: 100%;
	list-style-position: outside;
	list-style: none;
	padding: 0;
	margin: 0;
}

.ac_results li {
	margin: 0px;
	padding: 2px 5px;
	cursor: default;
	display: block;
	/* 
	if width will be 100% horizontal scrollbar will apear 
	when scroll mode will be used
	*/
	/*width: 100%;*/
	font: menu;
	font-size: 12px;
	/* 
	it is very important, if line-height not setted or setted 
	in relative units scroll will be broken in firefox
	*/
	line-height: 16px;
	overflow: hidden;
}

.ac_loading {
	background: white url('indicator.gif') right center no-repeat;
}

.ac_odd {
	border-bottom:1px dotted #cccccc;
}

.ac_even {
	border-bottom:1px dotted #cccccc;
}

.ac_over {
	background-color: #0A246A;
	color: white;
}
</style>

4. Add a input field to your html file

<INPUT id=ac1 TYPE="TEXT" class=nobold12  size=45 NAME="from" maxlength="90" VALUE='' >

(see autocomplete demo.html from here: http://solr-ra.tgels.org/demo_autocomplete.html)

Note: ac1 the id of the input field should be the same as the ac1 in the jquery script above.
If you have installed everything correctly autocomplete should be working now. Type a few characters like “san fra” and it should pull cities starting with “san fra”.

Note:
For Apache/PHP web tier:

1. You will need PHP with Pear/PECL extension (HTTP_Request2)

You can install php/Pear-PECL as follows on fedora:
yum install php
yum install php-pear
pear install HTTP_Request2
