 Configuration

 After installing the extension, all you need to do is to register it.

 After your next build, your project will no longer display raw markup in the search result excerpts.
 
+Since version 1.5.0, Sphinx is adding the source file extension to the source files it includes in the output folder.
+For example, when your source file extension is `rst` (specified in the config variable `source_suffix` as `[.rst]`,
+your index file appears in the output's source folder as `index.rst.txt`. If you use a Sphinx version lower than 1.5.0,
+it appears as `index.txt`. *Sphinx: pretty search results* considers this difference and changes its behavior according
+to your Sphinx version. However, if you use a Sphinx theme that expects the old file names although you are using a
+later Sphinx version, you can fall back to the old file names by setting the following configuration variable::
+
+   use_old_search_snippets = True
