Searchable dataObjects SS 4.5.1

<%- if @topic_view.topic.tags.present? %>
<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>
<% end %>

I have had success in the past using GitHub - g4b0/silverstripe-searchable-dataobjects: Searchable DataObjects is a module that permit to include DataObjects into frontend search but this does not seem to be compatible with SS 4.5.1

Can anyone point me in the right direction to get dataObjects to appear in the built in SS search?

I have seen other modules which impliment Solr, but I think I would like to avoid this.

Thanks in advance.
