The next phase of this project is to implement a search tool. The pieces we’ll need include:
- An interface where users can provide search terms and view results.
- A lookup mechanism that takes each search term and returns the pages that contain it.
- Mechanisms for combining search results from multiple search terms.
- Algorithms for ranking and sorting search results.
The general term for processes like this is “information retrieval”, which you can read more about at thinkdast.com/infret.
In this exercise, we’ll focus on steps 3 and 4. We’ve already built a simple version of 2. If you are interested in building Web applications, you might consider working on step 1.
