Cons
Con No AutoComplete/Suggest
Does not have the functionality to either autocomplete the users search query or suggest an alternative query ("Did you mean?").
Con No 'More like this'
CloudSearch doesn't support the 'More like this' or 'Find similar' features.
Con Propriety Tech
While ElasticSearch and Solr both have active open-source communities propelling the technology forward, CloudSearch is closed. This has multiple disadvantages such as:
- Constrained by what Amazon allows you to modify/customize.
- No transparency behind new feature development.
- Potentially slower development of new features.
- No way to modify/extend the search algorithms.
- No existing language specific API to call the Cloudsearch and process the response into objects.
Con No Geolocation search
No way to sort and filter by distance.
