Key Features of Amazon CloudSearch
Fully Managed Service:
CloudSearch is a fully managed service, which means you don’t need to worry about infrastructure management, scaling, or hardware provisioning.
Amazon handles the backend management, including software patching, server management, scaling, and backups.
Full-Text Search:
CloudSearch supports full-text search, enabling you to index and query large volumes of text-based data.
It provides powerful search capabilities such as phrase matching, stemming, wildcards, and fuzzy search to improve the relevance of search results.
Faceted Search:
CloudSearch supports faceted search, which allows you to categorize your search results dynamically. Users can filter search results based on specific fields, such as product categories, price ranges, and more.
This is particularly useful for e-commerce sites or content libraries where users need to filter results based on specific attributes.
Geo-Spatial Search:
CloudSearch offers geo-spatial search, which allows you to search and filter results based on location or distance.
This is useful for use cases like finding nearby stores, locations, or filtering results based on geographic proximity.
Real-Time Indexing:
CloudSearch supports real-time indexing of documents, meaning that any new data or updates to existing data are reflected in search results quickly, with minimal latency.
Multi-Language Support:
CloudSearch supports search indexing in multiple languages, including English, Spanish, French, German, Italian, Japanese, and more. This allows you to create a global search experience for your users.
Scalability:
CloudSearch automatically scales to handle growing data volumes and increasing traffic. It can scale horizontally by adding more search instances as needed to meet demand.
CloudSearch scales automatically based on traffic, ensuring high availability and low latency.
Customizable Ranking and Relevance:
You can configure the ranking of search results to make them more relevant for your users.
CloudSearch provides custom scoring and ranking expressions to prioritize certain attributes in search results.
Security:
CloudSearch supports IAM (Identity and Access Management) integration for fine-grained access control to your search domains.
Data is encrypted both in transit and at rest using SSL/TLS and AWS KMS (Key Management Service).
You can control access to search domains by restricting access to specific IP addresses or through VPC (Virtual Private Cloud).
Cost-Effective:
CloudSearch uses a pay-as-you-go pricing model, so you only pay for the resources you use.
Pricing is based on the number of search instances, storage, and the data transfer you consume.
Analytics:
CloudSearch provides usage logs and search analytics to help you understand user behavior, improve search relevance, and monitor the performance of your search domain.
