Switching from Search API Database to Solr i have a site which is already using Search API database and Facets search hosted on Acquia. The site main search (recipe search) is a  view with exposed filters to display search and similar content etc. And the site is in 2 languages ( EN and Arabic )

I need to implement spellcheck (did you mean) in the site and this module is only available for Solr.

I have no experience with Solr search. My question is how easy it will be to switch to Solr? Will i have to create different VIEW etc?

I have done a lot of theming, i am afraid of doing that all work again.

What is your expert opinion.

thanks :)
You will need to switch search server for your search index. But I think your view can stay as configured now as it targets a index (which only will change server).

You will also need the module Search API Spellcheck. Then add the "Search: Spellcheck" field to the header of your view. This will output the message “Did you mean "something" in the header if a suggestion is returned by Solr.

You will find the setting for which server your index should use under your index.
