📰 Medium · RAG

Learn how hierarchical indices work by mimicking human search behavior in long documents, improving search efficiency

intermediate Published 13 May 2026
Action Steps
  1. Build a hierarchical index by dividing a document into sections and subsections
  2. Apply a search algorithm to find the relevant section first
  3. Configure the algorithm to then search for the relevant sentence within the section
  4. Test the efficiency of the hierarchical index against a traditional index
  5. Compare the results to evaluate the effectiveness of the hierarchical approach
Who Needs to Know This

Developers and researchers working on information retrieval and natural language processing can benefit from understanding hierarchical indices to improve search algorithms
