Result Processing

We base our search result handling on the same template provided with GSA — Customized. But, you can build your own.

  • Remove SERP <head> content to wrap with your template.
  • Replace references to search in links and form action to point at your new page.
  • Review settings in top of GSA default XSL for configurable options.
  • Remove or fine-tune page top & bottom content.
  • Remove conflicting CSS.
