Amazon CloudSearch vs Amazon Kendra: What are the differences?


Amazon CloudSearch and Amazon Kendra are both services provided by Amazon Web Services (AWS) that offer search functionality. While both services enable users to build search applications, there are several key differences between them.

1. Scalability and Performance: Amazon CloudSearch is designed to handle large data volumes and support high query volumes. It automatically scales to meet the demands of increasing data or query loads. On the other hand, Amazon Kendra is optimized for enterprise search scenarios, providing intelligent search capabilities with natural language processing and machine learning. It focuses more on delivering highly relevant search results rather than handling massive data volumes or query loads.

2. Search Algorithm Complexity: Amazon CloudSearch provides a simpler search algorithm, where users can perform simple searches with basic queries and filters. It offers features like faceting, sorting, and relevancy ranking. In contrast, Amazon Kendra employs more advanced search algorithms, including natural language understanding and contextual relevance. It is capable of understanding complex queries, extracting relevant information, and returning highly accurate results.

3. Search Types and Data Sources: Amazon CloudSearch supports search and retrieval across documents and objects indexed in it. It is primarily used for searching structured data, such as product catalogs or text documents. On the other hand, Amazon Kendra is designed for unstructured data search, including text documents, PDFs, presentations, and forums. It excels in understanding and searching through unstructured content, making it suitable for use cases like knowledge management systems.

4. Customization and Integration: Amazon CloudSearch offers more customization options, allowing users to control the indexing and search behavior using configuration files and APIs. It provides flexibility in defining fields, their types, and search ranking. Conversely, Amazon Kendra is more of a managed service with less customization options. It focuses on simplicity and ease of use, providing pre-built connectors for various data sources and AI-based search capabilities.

5. Cost Structure: Amazon CloudSearch charges based on the instance size and the number of search or document batch requests. It offers multiple pricing tiers depending on the instance capacity. In contrast, Amazon Kendra pricing is based on the number of queries and the amount of data processed. It does not require any upfront payment and offers pricing based on different tiers according to query volume.

6. Query Capabilities: Amazon CloudSearch provides basic search capabilities like keyword matching, boolean operators, and filtering by fields. It supports both simple and structured searches. On the other hand, Amazon Kendra offers advanced query capabilities like natural language processing, synonyms, and personalized search. It can understand user intent, provide automatic suggestions, and deliver highly relevant results based on context.

In Summary, Amazon CloudSearch is a scalable search service suitable for structured data, while Amazon Kendra is an AI-powered search service optimized for unstructured data, offering advanced search algorithms and enterprise search capabilities.
