Vue JS Searching all record

Question

I can only search the data within the page.. Is there a possible solution on searching all the data

(function () {
    'use strict';
    // Replace with your Custom View's view ID
    var customViewID = 6387076;

    var vm = new Vue({
        data: {
            searchText: '', // Add a section for search text to the data object
            records: [],
        },
        computed: {
            // Create a function to filter
            filteredRecords: function () {
                var self = this;
                return self.records.filter(function (record) {
                    return record.employeename.value.indexOf(self.searchText) !== -1;
                });
            }
        },
    });

    kintone.events.on('app.record.index.show', function (event) {
        if (event.viewId !== customViewID) return event;
        var records = event.records;

        // Mount the Vue instance on the HTML element with ID #app in the custom view
        vm.$mount('#app');

        // Set the data
        Vue.set(vm, 'records', records);
        return event;
    });
})();

I just want to view the data where name is like to record
