sensitive

If true, specifies that string-based filtering must be performed in a case-sensitive manner. By default all string-based filtering is case-insensitive:

var dataSource = new shield.DataSource({
    //include only category names starting with capital "S"
    filter: {
        path: "category.name",
        filter: "startswith",
        value: "S",
        sensitive: true
    }
});
