Live Search functionality in sapui5 list control

Pre-requisites

1.sapui5 framework
2.basic javascript knowledge

What we are going to do is simple.We have a List with data.We also have a Search field.When we search the data in the list is refined based on the searchfield you entered live.We are using liveChange event of sap.m.SearchField control to achieve this.



Steps

1.Create a list and bind data to the list.

var oModel = new sap.ui.model.json.JSONModel({
    "Data": [{
        "firstname": "ricky",
        "lastname": "martin"
    }, {
        "firstname": "philip",
        "lastname": "morrs"
    }, {
        "firstname": "arnold",
        "lastname": "schwarzenegger"
    }]
});
sap.ui.getCore().setModel(oModel, "myModel");


oList = new sap.m.List("oList", {});
oListItem = new sap.m.StandardListItem({
    title: "{firstname} {lastname}"
});
oList.setModel(sap.ui.getCore().getModel("myModel"));
oList.bindAggregation("items", "/Data", oListItem);

2.Create search field control.
 searchL = new sap.m.SearchField({});
3.Get the search field value.
 var like = evt.getSource().getValue();


4.Implement search in liveChange event.
 liveChange:function(evt) {
    var like = evt.getSource().getValue();
    var binding = sap.ui.getCore().getControl("oList").getBinding("items");

    var filters = [
        new sap.ui.model.Filter("lastname", sap.ui.model.FilterOperator.Contains, like),
        new sap.ui.model.Filter("firstname", sap.ui.model.FilterOperator.Contains, like)

        // Add additional filters  
    ];
    var oFilter = new sap.ui.model.Filter({
        aFilters: filters,
        bAnd: false,
        _bMultiFilter: true
    }); // true = AND, false = OR  

    binding.filter(oFilter);
},
tooltip: "Search for objects..",
});

If we set bAnd to true both filters are AND ed.Here we are using OR functionality ie either firstname or lastname contain search value it will show up.
