In a Nutshell

Build a high-performance search engine index using Tries and Hashing to search through thousands of documents instantly. This hands-on tutorial focuses on practical implementation of search engine index project concepts.

Capstone Project: Search Engine Index

In this project, you will apply your knowledge of Tries and Hashing to build the core indexing component of a search engine.

1. The Challenge

Searching through a massive list of documents linearly for a keyword is $O(N \times L)$. We want to find documents containing a prefix or a word in $O(L)$ time, where $L$ is the word length.

4. Key Learnings

  • Tries are perfect for auto-complete and prefix matching.
  • Hash Maps (Inverted Index) are the standard way to map keywords to documents in modern search engines like Elasticsearch.
