title: searching with elasticsearch js with multiple fields
body: <p>Hi guys I have this code :</p>
  
  <pre><code>let test = await client.search({
        index: 'test',
        type: 'doc',
        body: {
          query: {
            match: {
              title: 'something',
            }
          }
        }
      });
  </code></pre>
  
  <p>this code is searching by 1 query which is title: 'something' , but I want to change it to search with multiple keys, for example:</p>
  
  <pre><code> let test = await client.search({
            index: 'test',
            type: 'doc',
            body: {
              query: {
                match: {
                  title: 'something',
                  desc: 'some Qualifications'
                }
              }
            }
          });
  </code></pre>
  
  <p>but this code doesn't work and I can't find anything that will work like that, can anyone help?</p>
