Implement full text search using DSpace OpenSearch API

[mzarafon]

The API call looks like this:

https://scholarship.tricolib.brynmawr.edu/open-search/discover?query=" . $query . "&scope=10066/4022&order=DESC&rpp=20&sort_by=0&page=1&etal=0

Where $query is the search query

From previous Drupal project: `<?php
//section header
echo "

Full Text Search

";

//get current url to find out what the user searched
$url = $_SERVER["REQUEST_URI"];
$index1 = strpos($url, "site/") + 5;
$index2 = strpos($url, "?");
if($index2 === false){
$query = substr($url , $index1 );
}else{
$query = substr($url , $index1 , $index2-$index1 );
}

//Narrow Scope to Just AQSI Statements

//Open Search does everything in D-Space

//convert weird character codes like '&' and spaces into the right code for Dspace
$query = str_replace("%25", "%", $query );
$more_url = "https://scholarship.tricolib.brynmawr.edu/open-search/discover?query=" . $query . "&scope=10066/4022&order=DESC&rpp=20&sort_by=0&page=1&etal=0";
echo "

<a href="" . $more_url . "">Narrow Results- (Search only AQSI Statements)

";

//Open Search feed for DSpace
$feed_url = "https://scholarship.tricolib.brynmawr.edu/open-search/discover?query=" . $query . "&format=rss&rpp=100&scope=10066/4022";

// Debugging code for OpenSearch queries to make sure the API call is formatted correctly -Mike Z//

// echo "

" . $feed_url . "

";

// End debugging code //

//get the xml file associated with that search

//this will have all the data including title, link, and description

//we will format this file to full the full text search with data
$data = file_get_contents($feed_url);

//get rid of the extra tags at the top of the document

//this is extra information about the feed that we don't need
$header_index = strpos($data, "");
$data = substr($data , $header_index);

//get each individual entry, so we can go through it one at a time in our for loop
$array = explode("" , $data);
$len = count($array);

//formatting to match regular searches
echo "<ol class="search-results apachesolr_search-results">";

//first one is empty not sure why, but there's no data there, so we'll skip it

//the first statement starts at index 1
for ($i=1; $i<$len; $i++){
//Statement Title
$index1 = strpos($array[$i], "<title>") + 7;
$index2 = strpos($array[$i],"</title>" , $index1);
$title = substr($array[$i] , $index1 , $index2-$index1 );
//url to the statement
$index1 = strpos($array[$i], "<link") + 6;
$index2 = strpos($array[$i], "/>" , $index1);
$statement_location = substr($array[$i] , $index1 , $index2-$index1 );
//statement description
$index1 = strpos($array[$i], "<summary type="text">") + 21;
$index2 = strpos($array[$i], "" , $index1);
$description = substr($array[$i] , $index1 , $index2-$index1 );
//published date
$index1 = strpos($array[$i], "") + 11;
$index2 = strpos($array[$i], "" , $index1);
$date = substr($array[$i] , $index1 , $index2-$index1 );
//format the date
$year = substr($date , 0 , 4 );
$month = substr($date , 5 , 2 );
$day = substr($date , 8 , 2 );
$date = "( $month - $day - $year)";
//print out this data and format it the same way as the Apache Solr searches

}
