To create a custom search adapter you will need to subclass the BaseSearch class. Then create an instance of the new class and pass that as the search keyword argument when you create the WebSupport object:
support = WebSupport(srcdir=srcdir,
builddir=builddir,
search=MySearch())
For more information about creating a custom search adapter, please see the documentation of the BaseSearch class below.
Defines an interface for search adapters.
The following methods are defined in the BaseSearch class. Some methods do not need to be overridden, but some (add_document() and handle_query()) must be overridden in your subclass. For a working example, look at the built-in adapter for whoosh.
