title: angular-in-memory-web-api for query params other than object attributes
body: <p>I have a collection of book objects in memory,</p>
  
  <pre><code>book { title: string, author: string, description: string }
  </code></pre>
  
  <p>Now the url for searching book is</p>
  
  <pre><code>api/books/search/{text}
  </code></pre>
  
  <p>the real web api does check for matches in all attributes of books including author, title and description.</p>
  
  <p>In the angular-in-memory-web-api I can have urls like, </p>
  
  <pre><code>api/books/?title={text}
  api/books/?author={text}
  </code></pre>
  
  <p>etc.</p>
  
  <p>Is there any way to have <em>api/books/search/{text}</em> this url working with the angular-in-memory-web-api?</p>
