Parse HTML pages. Create inverted index. Search for pages

A search engine which takes keywords as queries and retrieves a ranked list of results

A search engine that takes keyword queries as input and retrieves a ranked list of relevant results as output. It scraps a few thousand pages from one of the seed Wiki pages and uses Elasticsearch for a full-text search engine.
