Hi @Daus Shah 

After playing around with Wijmo FlexGrid APIs on their website, I managed to find a way (even though complex) to change the search algorithm.
The way to achieve that requires some complex custom JavaScript that I was able to simplify to the following:

- Add the following code in a JSNode in Grid’s OnInitialize event handler:

wijmo.grid.search.FlexGridSearch.prototype._applySearch = function () {  
    var e = this._g;  
    this._rxSrch = this._rxHilite = null;  
    var t = this.text.replace(/([.?*+^$[\]\\(){}|-])/g, '\\$1');  
    if (t.length) {    
        var r = e && e.caseSensitiveSearch ? 'g' : 'gi';    
        this._rxSrch = new RegExp('(?=.*' + t + ')', r);    
        t = wijmo.escapeHtml(t);    
        this._rxHilite = new RegExp('(' + t + ')(?![^<]*>)', r);  
    }  
    var i = e ? e.collectionView : null;  
    i.sourceCollection && i.refresh && i.refresh();
};

// Being $parameters.GridWidgetId the Grid block identifier

- Here's the final result:
 

Hope it helps!

Cheers,
