Industry Algorithm Edition

Applicable to enterprises and developers who require a one-stop solution for quickly constructing intelligent industry-specific search systems, industry best practices, industry query analysis algorithms, industry sort models, customized tuning models, and reliable search performance. Key industries include e-commerce, gaming, content community operations, and education.

• Provides intelligent search algorithm models and best practices for multiple industries such as e-commerce, content community operations, and gaming.

• Allows you to customize exclusive word segmentation and natural language processing (NLP) algorithm models based on your business requirements.

• Offers search guide features such as drop-down suggestions, top searches, and hints, and supports manual intervention.

• Serves as an out-of-the-box service edition which frees you from O&M and allows you to complete the end-to-end configuration of intelligent industry-specific search with a few clicks.

High-performance Search Edition

Applicable to enterprises and developers who require high performance in big data search scenarios, such as searches for orders, coupons, logistics, and insurance policies. High-performance Search Edition provides a one-stop solution for the quick construction of search systems in a cost-efficient manner.

• Allows you to retrieve hundreds of billions of data within milliseconds and provides solutions for searches of orders, logistics, insurance policies, and more.

• Supports connection to Alibaba Cloud services with a few clicks, such as ApsaraDB RDS, MaxCompute, and PolarDB. You can connect to self-managed databases by calling API operations or using SDKs.

• Provides multiple search modes such as combined search, powerful full-text search, and fuzzy search with a prefix, a suffix, or an infix.

• Supports scaling with a few clicks, which frees you from O&M on underlying clusters and enables you to flexibly cope with different business scenarios.

Vector Search Edition

Applicable to enterprises and developers who have online vector retrieval requirements for scenarios such as graph or text searches, audio or video searches, NLP vector searches, Q&A, recommendation, and risk monitoring. Vector Search Edition is also suitable for those who are concerned about the performance, effectiveness, and stability of the search service.

• Performs deep optimization for vector retrieval scenarios, so that multiple scenarios such as graph searches, audio and video searches, personalized recommendations, and Q&A are supported.

• Supports 1 billion 128-dimensional vectors or thousands of queries per second (QPS) within milliseconds even when the service is of the minimum specifications.

• Provides multiple built-in vector retrieval algorithm models to support searches based on primary keys, vectors, and namespaces.

• Adopts highly available engineering architecture, supports horizontal scaling of data, ensures data timeliness, and safeguards system reliability for highly concurrent retrieval.

Retrieval Engine Edition

Applicable to enterprises and developers who have large-scale text retrieval scenarios and require a high-performance, cost-effective, and customized search service.

• Provides multiple built-in flexible indexing and search policies to support high-performance retrieval of a large amount of big data.

• Allows you to retrieve hundreds of billions of data within milliseconds and synchronize the updated data within milliseconds.

• Provides multiple built-in vector retrieval algorithm models to support combined search modes such as tag and text inverted indexes and vector indexes.

• Supports a wide range of custom SQL functions, engine plug-ins, and algorithm models, so that you can flexibly customize your business processing logic.

• Allows you to use standardized SQL programming languages and integrated development environments (IDEs) to reduce the cost of engine learning and development.
