Improve Search by not indexing the Frontpage

[erictuvesson]

Documentation Bug report

Describe the bug

"Creating a Backend" link is going to the frontend providing no value in the search results.

To Reproduce

The link goes to the frontpage.

Expected behavior

To not index the frontpage, there is no reason why you would be searching for it.

Additional context

Right now the search is not perfect, and is quite a big task to improve.
Ideally we should create separate issues for search, but all the issues are very linked together.
