You can try this solutuion

I have create a demo on stackblitz

Search Pipe

transform(value: any, args?: any): any {
    if (!args) {
      return value;
    }
    return value.filter((val) => {
      let rVal = (val.id.toLocaleLowerCase().includes(args)) || (val.email.toLocaleLowerCase().includes(args));
      return rVal;
    })

}

html code

<tr *ngFor="let customer of users | customerEmailFilter:email;let i = index">
    <th scope="row">{{i+1}}</th>
    <td>{{customer.id}}</td>
    <td>{{customer.email}}</td>
</tr>

ts file code

users=[{
    id:'123',
    email:'abc@gmail.com'
  },{
    id:'1234',
    email:'xyz@hotmail.com'
  },{
    id:'12345',
    email:'jsgsbh@kk.com'
  },{
    id:'123456',
    email:'test@gmail.com'
}]
