Allow Case insensitive search in AutoComplete while filtering using both text and value


I followed the instructions here: https://ej2.syncfusion.com/javascript/documentation/auto-complete/how-to/filter/ to use autocomplete on text and value. This works great except that the search is not case-insensitive for either of the fields. For example, if I type the search as au instead of Au, it does not find anything.

I thought the predicate operator 'contains' by default was case-insensitive.

Can you please look into it?

Hi Tera,

We suggest you use the ignoreCase property for your requirement. When the ignoreCase property is set to ‘false’, consider the case-sensitive on performing the search to find suggestions.

filtering: function (e) {

    e.preventDefaultAction = true;

    var predicate = new ej.data.Predicate(




      (ignoreCase = true)


    predicate = predicate.or('Code''contains'e.text(ignoreCase = true));

    var query = new ej.data.Query();

    query = e.text != '' ? query.where(predicate) : query;
