Hello, @webdes Thanks for reaching out to the community.
With a big budget Swiftype is a good tool, but seriously expensive. I’ve used Google Search before, it’s either free or cheap ($100/Yr with no ads) with some success, although it’s boring and I find that clients don’t like it… Often times I am waiting for Google to Index the right pages for my search and customizing it isn’t always easy.
I would suggest looking into Algolia search, it’s super quick. It can be as simple or advanced as you need it to be.
You can see an example of it here (A decent integration, on one of my sites)
Oh yeah, and it’s free for up to 10,000 instances/searches per Month
