I've had great experiences with algolia. I've used it on numerous client projects, and my own product https://appapp.io https://appapp.io . It is great as an out of the box search solution that will probably fit 90% of cases. It is blindingly fast and my clients love it. I expect there are some cases where elastic or solr will be a better fit; but these are most definitely edge cases for very specific search requirements. Algolia is a killer app for generic 'good' search.
