title: Use list of String as a parameter in elastic4s termsQuery
body: <p>I use as elastic4s library to communicate with ElasticSearch. I would like to make an equivalent of "SELECT * FROM WHERE MY_INDEX MY_FIELD IN (VALUE_1, VALUE_2, ....)"</p>
  
  <p>I produced that query </p>
  
  <pre><code>val req = search in indexName -&gt; {query indexType
     {bool
       must (
         termsQuery ("myField" transformed (myListOfValues))
       )
     }
  }
  </code></pre>
  
  <p>The method termsQuery is defined as follows in elastis4s</p>
  
  <pre><code>def termsQuery (field: String, capital gains: AnyRef *): TermsQueryDefinition
  </code></pre>
  
  <p>How can I turn my myListOfValues list to a AnyRef *</p>
  
  <p>Thank you for your help.</p>
