OpenSearch Scenarios
Conversational search service
The LLM-based conversational search service provides users with excellent search experience, efficiently improves the information acquisition efficiency, and increases the conversion rate of business.
OpenSearch LLM-Based Conversational Search Edition has the following benefits:
Dedicated conversational search services for enterprises
Builds dedicated conversational search services for enterprises based on business data. This makes conversation results more accurate and secure.
Multimodal search results
Supports multimodal search results such as answers, URLs, and images. This provides users with better search experience.
Low cost, easy to use
One-stop service that can be quickly connected. You can complete POC testing within 1 hour. The service is fully managed and O&M-free. You can use the service without deploying it.
Image Search
Images are typical unstructured data in AI field, which can carry more information, but cannot complete the retrieval by traditional split word recall.
Open Search vector search version can help customers abstract image data into vector features, build vector index based on the features, compare the vector data of the image under investigation with the vector index when querying, recall the vector with the closest distance to the image under investigation, and complete image retrieval.
Typical application scenarios include: image search (image search shopping, same price comparison), text search, photo search, image recognition, etc.
E-Commerce and O2O
The e-commerce and O2O scenarios have extremely high requirements for the retrieval and sorting of search results.
Better intent identification
The Industry-Specific Enhanced Edition for E-Commerce of OpenSearch provides industry-specific analyzers and a query analysis feature for better intent identification.
Common sort expressions for e-commerce
The Industry-Specific Enhanced Edition for E-Commerce also provides common sort expressions for e-commerce, which can meet sorting requirements without additional configurations.
Built-in algorithm models
OpenSearch provides built-in algorithm models for top searches, hints, and drop-down suggestions.
Content, Communities, and Forums
In the media industry, search keywords and content are diversified and may not follow word usage standards. In this scenario, intelligent semantic analysis is required.
OpenSearch allows customers in the content industry to customize models for term weight analysis, spelling correction, and query rewriting and identify the query intent using AI.
After algorithm tuning, popularity models can quantify the static quality and popularity degree of each commodity and generate popularity scores. This way, you can construct a more fine-grained sort model to meet your search requirements precisely.
Big Data Query in Enterprises
The data of enterprises involves multiple dimensions, and the data amount increases continually. In addition, enterprises require efficient data updates. In this scenario, a search engine that provides powerful capabilities and high performance is required.
The search engine of OpenSearch features auto scaling, simple syntax, convenient debugging, high stability, and cost-effectiveness.
OpenSearch can respond in seconds to the requests that search for updated data, which ensures data timeliness. OpenSearch also combines query analysis with intervention to better identify the query intent.
