I tried to use those and they didnt work - I’m not sure why. I tried both of them and got “no search results”.
The “Site Search” one has an FAQ attached and it looks like it doesnt search the current page. Also, I pulled directly from the FAQ:
Does site search scan all of the content on each page to find results?
A. No. Site search is intended as a lightweight, fast and efficient search solution. The
results for pages are filtered by the page name and keywords that are entered into a
pages keyword SEO settings.
So maybe it (and the other search option) do not search anything but the page name and keywords associated with the page - which won’t work for my purposes.
I have never used either of these, so I cannot tell you a great deal about how they work in practice. It wouldn’t be my first choice, but you could probably install Google search on the website. Add custom search to your site - Programmable Search Engine Help
@JLK no these 2 search brics do not search the site content. It‘s why they are also useless for me. But there exists somewhere in the forum a post how to add it manually.
