OpenSearch High-performance Search Edition provides two types of analyzers: text analyzer and custom text analyzer.
Analysis is a basic but important feature of search engines. Analysis results directly affect search performance. The meaning of a phrase varies with different business scenarios and contexts. Therefore, the expected analysis results change based on diversified business scenarios. In addition to basic analyzers that apply to all industries, OpenSearch provides industry-specific analyzers, such as the analyzer for text from the E-commerce industry. For more information, see Text analyzers.
To meet diversified business requirements, OpenSearch allows you to create a custom analyzer by using a built-in analyzer and intervention entries. You can select analyzers when you configure index fields for an application. This way, OpenSearch can adjust the process of analysis during indexing and searches to ensure that search results meet your expectations. For more information, see Custom text analyzers.
