A search engine built to retrieve geographical information of any country.

Apache Nutch is used to crawl the relevant web pages from the 50 seed URLs given.

Apache Solr is used to index the crawled web pages. The default page rank model of indexing using solr gives satisfactory results. The results are further improved by implementing and applying HITS algorithm.

The results obtained using different indexing methods, different clustering methods and different query expansion methods are compared with the results obtained on the same query using Google and Bing.

Both flat clustering (K-means) as well as hierarchical clustering (single-link) is used to group similar web pages together, and improve search results.

Associative, metric and scalar clustering are used to get the new, modified, enhanced expanded query to improve search results.
