Have not seen any tutorials on multiple item reference fields since their release. In particular setting up searches of these fields

Hi,
You can use include() to get multiple reference fields by adding the name of the referenced collections:

import wixData from 'wix-data';

// ...

wixData.query("books")
  .include("author", "publisher")
  .find()
  .then( (results) => {
    if(results.items.length > 0) {
      let books = results.items;
      let firstBook = items[0];
      let firstAuthor = firstBook.author;
      let firstAuthorBio = firstAuthor.bio;
      let firstPublisher = firstBook.publisher.name;
    } else {
      // handle case where no matching items found
    }
  } )
  .catch( (error) => {
    let errorMsg = error.message;
    let code = error.code;
  } );

In this example there is a books collection which has two reference fields that reference an authors collection and a publishers collection.
The query includes the author and publisher properties so that each returned book will also include the full items of its referenced author and publisher.
Check out the API here.

Good luck :slight_smile:
