Can I use the Search API module?

Yes, you can use the Search API module with Acquia Search. This is an alternative to using the Apache Solr Search module. Acquia Search for the current Drupal version requires the use of Search API, and won’t use the ApacheSolr module.

Don’t use both the Search API module and the Apache Solr Search module in the same environment.
