title: Search for files & file names using silver searcher
body: <p>Using Silver Searcher, how can I search for:</p>
  
  <ol>
  <li>(non-binary) files with a word or pattern <strong>AND</strong></li>
  <li>all <em>filenames</em>, with a word or pattern including filenames of binary files.</li>
  </ol>
  
  <p>Other preferences: would like to have case insensitive search and search through dotfiles.</p>
  
  <hr>
  
  <p>Tried to alias using this without much luck:</p>
  
  <p><code>alias search="ag -g $1 --smart-case --hidden &amp;&amp; ag --smart-case --hidden $1"</code></p>
