RediSearch 2.0 has been released into public preview with new features driven by user feedback, focusing on improving developer experience and scalability. The new data indexing capabilities allow users to create an index associated with their data and use the query engine to search and query the data using secondary indices. With RediSearch, developers can easily add an index to an existing application without changing code, making it easy to manage and query complex queries. The full-text search engine allows for powerful queries à la Google, including prefix matches, fuzzy search, unions, and tag field search. Additionally, RediSearch includes data aggregation capabilities that are covered in the documentation, tutorial, and online course.
