Some important stuff from today's lecture that I picked up on Information Retrieval are:
1. Don't throw away partial matches. If something isn't exactly a 100% match that doesn't mean it isn't relevant!
2. Weighted matches should be allowed. Unique words should be labeled are more important that common words!
3. Size of a document should be ignored. The length of the document shouldn't affect its relevance because it is possible that it is just the same document attached to itself several times, that wouldn't make the document more relevant.
