Bing API search in dotCMS (using JSON)

## Bing API search in dotCMS (using JSON) - With page numbering, spelling suggestion, and "deep links"
## Search form on page submits to same page



## THIS CODE WILL NOT WORK AS OF AUGUST 1, 2012 - The Bing Search API has been deprecated in favor of a paid service.
## We're switching to Google Site Search XML


<form action="${VTLSERVLET_URI}">
	<div>
		<input id="box" type="text" name="q" size="15" maxlength="255" value="" />

		<input type="submit" value="Submit" /><br />

	</div>
</form>


####################Bing API Search results


##### Set some variables manually

#set($resultsperpage=5)
#set($sites=$UtilMethods.encodeURL("(site:www.yoursite1.com OR site:www.yoursite2.com OR site:www.yoursite3.com)"))


##### Set some variables using the query string (e.g. www.yoursite.com/?q=kermit&p=4)

#set($mySearch=$UtilMethods.encodeURL($request.getParameter("q")))

## Get page number from query string if it exists, otherwise default to "1"
#if($UtilMethods.isSet($request.getParameter("p")))
	#set($pagenumber=$webapi.parseInt($request.getParameter("p")))
#else
	#set($pagenumber=1)
#end

## Determine what the next and previous page numbers are
#set($nextpage=$math.add($pagenumber,1))
#set($prevpage=$math.sub($pagenumber,1))

## Use the page number and results per page to figure out the offset of results
#set($resultsoffset=$math.mul($resultsperpage,$math.sub($pagenumber,1)))
#if($pagenumber!=1)
	#set($resultsoffset=$math.add($resultsoffset,1))
#end



## Load the JSON from Bing
#set($appId="YOURBINGAPPID") ## Get it here: http://www.bing.com/developers/
#set($path = "http://api.bing.net/json.aspx?AppId=$!{appId}&Version=2.2&Query=$!{mySearch}+$!{sites}&Sources=web+spell&Web.Count=$!{resultsperpage}&Web.Offset=$!{resultsoffset}&JsonType=raw")
#set($myjson = $json.fetch("$path"))

## Displays the JSON address for debugging purposes. Can safely be removed
<p><b>Address:</b> $path</p>

<h1>Searching for "$!{request.getParameter('q')}"</h1>

## Use Bing's spelling correction if it thinks there's a more likely spelling
#foreach ($spelling in $myjson.SearchResponse.Spell.Results)
       <p>(maybe you meant "$!{spelling.Value}"?))</p>
#end

### Figure out which of results we're showing - The first result is "1" on the first page, even though offset is "0"
#set($firstshown = $resultsoffset)
#if($firstshown ==0)
	#set($firstshown=1)
#end


#set($lastshown = $math.sub($math.add($firstshown,$resultsperpage),1))
#set($lastshowndisplay = $lastshown)

## Tweak the display to show correct last number if on the last set of results
#if($lastshown > $myjson.SearchResponse.Web.Total)
	#set($lastshowndisplay = $myjson.SearchResponse.Web.Total)
#end

<p>Showing results: $firstshown to $lastshowndisplay of $myjson.SearchResponse.Web.Total</p>
<ul>
	#foreach($result in $myjson.SearchResponse.Web.Results)
		<li>
			<h2><a href="$result.Url">$result.Title</a></h2>
			<p>$!{result.Description}</p>
			<a href="$result.Url">$result.DisplayUrl</a> ( <a href="$result.CacheUrl">Cached</a> )
			#if($UtilMethods.isSet($result.DeepLinks))
				<ul>
					#foreach($deeplink in $result.DeepLinks)
					<li><a href="$!{deeplink.Url}">$!{deeplink.Title}</a> </li>
					#end
				</ul>
			#end
		</li>
	#end
</ul>


##Only display "previous" link if we're not on the first page
#if($myjson.SearchResponse.Web.Offset != 0)
	<a href="${VTLSERVLET_URI}?q=$UtilMethods.encodeURL($request.getParameter('q'))&p=${prevpage}" class="previousresults">Previous Results</a>
#else
	<span class="previousresults">Previous Results</span>
#end

##Only display "next" link if we're not on the last page
#if($lastshown <= $myjson.SearchResponse.Web.Total)
	<a href="${VTLSERVLET_URI}?q=$UtilMethods.encodeURL($request.getParameter('q'))&p=${nextpage}" class="nextresults">Next Results</a>
#else
	<span class="nextresults">Next Results</span>
#end
