In this project, you will implement a content-based recommender via an web app by
recommending similarity-based Java programming wikibooks content to
[login to view URL] data set (10 posts ONLY).
1. crawl java programming wikibooks pages
2. use Apache Lucene (and/or SOLR) or any Lucene compatibles to index crawled
content
3. build a simple web app to display the provided StackOverflow 10 posts, by selecting
each post, list the top 10 relevant wikibooks items (from your indexed
documents).
