The primary differentiator of CloudSearch is how simple it makes the lives of the developers using it. Not only does it automatically scale, developers can change search parameters, fine tune search relevance, and apply new settings at any time without having to upload the data again and can do so from a simple dashboard.
CloudSearch also automatically takes care of:
- Hardware provisioning
- Data partitioning,
- Software patches.
CloudSearch dynamically scales as the amount of searchable data increases or as the query rate changes. The search system utilizes well-understood and automated sharding and replication to scale.
CloudSearch will automatically add search instances and index partitions as required as well as add and remove replicas to respond to changes in search request traffic.

Pro Language-agnostic & typo tolerance
Algolia's engine has been built in such a way that you can index and search any language, or even several languages at the same time.
The engine is also typo tolerant, and will allow for up to two typos in each words of the search query.
This typo tolerance feature is also language agnostic, as it relies on optimized data structures and "fuzzy" tree traversals (implementing a Damarau-Levenshtein distance algorithm) instead of using dictionaries.
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 'More like this'
CloudSearch doesn't support the 'More like this' or 'Find similar' features.
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 Geolocation search
No way to sort and filter by distance.
There is a Free tier limited to 10k records that can only do 100k operations.
