title: Where is the search-theme-form.tpl.php file located in a drupal site or template?
body: <p>In Drupal (my one is v. 7), in a search module, the text "search" in search button is viewing by default. Probably the HTML structure behind this thing is like this:</p>
  
  <pre><code>&lt;input type="submit" value="Search"  /&gt;
  </code></pre>
  
  <p>I placed an image instead of the default search button image/bg color. I want to delete the <code>value="Search"</code> portion from the HTML <code>&lt;input/&gt;</code> tag.</p>
  
  <p>I went to modules/search, but there is no such file with a <code>&lt;input/&gt;</code> tag. So how come I remove the text?</p>
  
  <p>I got a solution, my so called '<em>Bangla Shamadhan</em>', from <a href="http://mydrupalblog.lhmdesign.com/theming-search-submit-button-css-cross-browser-compatible-solution" rel="nofollow noreferrer">http://mydrupalblog.lhmdesign.com/theming-search-submit-button-css-cross-browser-compatible-solution</a>.</p>
  
  <p>It's the <code>text-indent</code> thing:</p>
  
  <pre><code>#search-block-form input.form-submit, #search-form input.form-submit {
    height: 24px;
    width: 24px;
    cursor: pointer;
    text-indent: -9999px;
    border: none;
    background: url(images/mag_glass.jpg) no-repeat left top;
  }
  </code></pre>
  
  <p>The text is indented for unlimited spaces. It worked for me, but it's not a good practice to me.</p>

  <p>So, how can I edit the <code>&lt;input/&gt;</code> tag in a Drupal template or module to remove the attribute <code>value="Search"</code>?**</p>
