Increase Search Result Limit Beyond 50

Content Search Web Parts (CSWPs) and Search Result Web Parts (SRWPs, a.k.a Result Script Web Parts RSWPs) prevent more than 50 results being returned at once. This is true with or without paging enabled. This is true even if you provision the web part using XML. In older versions of SharePoint, it may allow you to enter a row limit greater than 50 but will then default to a mere 10 results.

I’m sure Microsoft has very good UX and technical reasons behind this limitation, however at 100 items I don’t feel that either UX nor performance suffer. I imagine that if using this technique for returning large page sizes (>100) that there is very real potential for bad performance and the UX is most likely appalling.

Importantly – this code should only be considered a learning tool. This code is entirely unsupported and generally just a really bad idea. Please be responsible 🙂

Recognition to Matt Stark who provided this solution. All I have done is rewritten it a bit for safety and I wanted to prefix it with a bit more discussion than it had. Original discussion is here.

The web parts which you want to act upon must be set to load asynchronously (this is not the default mode).
Edit Web Part > Change Query > Settings > Loading Behaviour :: Async option

Take note:

1. There are a few available solutions to this, none of which are much good, and even this one is should be considered a hack and be treated with caution.
2. I will only discuss this option as it is the best I have come across when considering the limitations of SharePoint Online.
3. Please only include this code on specific pages using a Content Editor or a Script Editor, and NOT globally.
4. I have amended the original code such that it only changes the row limit for those web parts which are set to return 50 items exactly.
5. I haven’t found any issues with this code, however I am using on a page that does nothing but display a list and in a situation where failure has limited impact on the system.
6. Apparently doesn’t work for anonymous users

And finally the code…

// <script type="text/javascript">
var CC = window.CC || {};
CC.CORE = CC.CORE || {};

CC.CORE.IncreaseSearchResultsMax = (function () {
    "use strict";

    var $ocreate = null;
    var newMaxItems = 100;
    var oldMaxItems = 50; // web part must be set to show this many items

    // on application initialization 
    // steal the global create variable and 
    // intercept calls to create UI widgets.
    Sys.Application.add_init(function() {
        $ocreate = $create;
        $create = updateResultCountCreate;
    });

    // listen to UI widget calls for CBS & DP
    var updateResultCountCreate = function (a,b){
        var ps = Array.prototype.slice.call(arguments, 0);  
        if(a === Srch.ContentBySearch && b.numberOfItems === oldMaxItems) { 
            b.numberOfItems = newMaxItems;
        }
        if(a === Srch.DataProvider && b.resultsPerPage === oldMaxItems) {
            b.resultsPerPage = newMaxItems;
        }
        $ocreate.apply(this,ps);  // apply the original $create method that we stole
    };
    return true;
})();
// </script>
