docs: add more information in searchContent()

[adydetra]

Can we get more information in the searchContent() section in the docs? It looks like a great feature and it would be great to see some more examples

for example, in useContent() there are many examples there that make it easier for us as nuxt content users.

I will Answered this discussion if the searchContent() docs have changed
