Add a Google search interface to FAQ pages

[splorp]

A suggestion from Frank Gründel.

Another thing we should consider is putting a search function on the FAQ
page. I did something similar with Google search for my site, and it was an
easy, fast and painless process. All you need is a Google account.

Here’s an example on his site:

Addendum from Frank:

I just created a search engine for NewtonFAQ using my own Google account. It should be sufficient if you put the following code somewhere near the top in the body section of http://newtonfaq.com/index.html:

<script async src="https://cse.google.com/cse.js?cx=4ad8d8669e62b4752"></script>
<div class="gcse-search"></div>

Keep me posted!
