title: Modifying dspace discover page in xmlui mirage theme
body: <p>I'm trying to modify the Mirage theme in DSpace 4.2 to cater to the specific needs of my organization. We want to add our own search box with custom search fields, and modify the search results page. </p>
  
  <p>This is how the default dspace search results page looks like:

  <p>After tinkering around with the <code>css</code> and <code>xsl</code> I came up with this layout:
  <img src="https://i.stack.imgur.com/Ou6jV.png" alt="enter image description here"></p>
  
  <p>The top search panel was added by me by modifying the <code>page-structure.xsl</code> file. Now, I want to remove the default search box which appears in the results page. I've looked into all the <code>css</code>, <code>xsl</code> and <code>sitemap</code> files. 
  By inspecting the sitemap files I found that the search is carried out by calling the <code>[dspace-source]/dspace-xmlui/src/main/java/org/dspace/app/xmlui/aspect/discovery/SimpleSearch.java</code> file. 
  I commented the code sections where the search box was being added, and re-built and re-deployed dspace, but still no success. </p>
  
  <p>Maybe, I'm not looking at the right files, due to lack of understanding.</p>
  
  <p>It would be nice if someone points me in the right direction.
  Thanks in advance</p>
