Hybrid search has emerged as a powerful approach to improve in-app product search, allowing developers to combine the strengths of semantic and lexical search techniques. By leveraging large language models (LLMs) and keyword-based retrieval, hybrid search systems can deliver more accurate search results, intuitive user interaction, and personalized engagement. This approach also supports cross-language searches and is critical for improving the experience for non-English-speaking users. Implementing hybrid search can lead to increased user loyalty, reduced onboarding friction and costs, improved customer satisfaction, better conversion rates, and new revenue streams. Hybrid search platforms like Vectara provide an end-to-end solution for developers, offering a simple-to-use API and comprehensive approach to search that yields the most comprehensive results.
