title: Elasticsearch match multiple fields
body: <p>I am recently using <code>elasticsearch</code> in a website. The scenario is, I have to search a string on a<code>field</code>. So, if the <code>field</code> is named as <code>title</code> then my search query was,</p>
  
  <pre><code>"query" :{"match": {"title": my_query_string}}.
  </code></pre>
  
  <p>But now I need to add another <code>field</code> in it. Let say, <code>category</code>. So i need to find the matches of my string which are in <code>category</code> :<code>some_category</code> and which have <code>title</code> : <code>my_query_string</code> I tried with <code>multi_match</code>. But it does not give me the result i am looking for. I am looking into <code>query filter</code> now. But is there way of adding two fields in such criteria in my <code>match</code> query? </p>
