    In case you're using systemjs - see configuration here.

    Import Ng2FilterPipeModule to your module

    import { NgModule } from '@angular/core';
    import { BrowserModule  } from '@angular/platform-browser';
    import { AppComponent } from './app';
     
    import { Ng2FilterPipeModule } from 'ng2-filter-pipe';
     
    @NgModule({
      imports: [BrowserModule, Ng2FilterPipeModule],
      declarations: [AppComponent],
      bootstrap: [AppComponent]
    })
    export class AppModule {}
     

    And use pipe in your component

    import { Component } from '@angular/core';
     
    @Component({
      selector: 'example-app',
      template: `
        <div>
            <input type="text" [(ngModel)]="userFilter.name" placeholder="name">
            <ul>
              <li *ngFor="let user of users | filterBy: userFilter">{{ user.name }}</li>
              
              <!-- in case you want to show empty message -->
              <li *ngIf="(users | filterBy: stringFilter).length === 0">No matching elements</li>
            </ul>
        </div>  
      `
    })
     
    export class AppComponent {
      users: any[] = [{ name: 'John' }, { name: 'Jane' }, { name: 'Mario' }];
      userFilter: any = { name: '' };
    }

    $or matching

    Use $or to filter by more then one values.

    $or expects an Array.

    In your component:

    // your array
    const languages = ['English', 'German', 'Russian', 'Italian', 'Ukrainian'];
    // your $or filter
    const filter = { $or: ['German', 'English'] };

    In your template:

    <div *ngFor="let language of languages | filterBy: filter">
      {{ language }}
    </div>

    Result:

    <div>English</div>
    <div>German</div>

    $or example with nessted values

    In your component:

    // your array
    const languages = [
      { language: 'English' },
      { language: 'German' },
      { language: 'Italian' }
    ];
     
    // your $or filter
    const filter = {
      language: {
        $or: ['Italian', 'English']
      }
    };

    In your template:

    <div *ngFor="let object of languages | filterBy: filter">
      {{ object.language }}
    </div>
