• Mapping, Cleanup
• Indexing

And searching

• Scoring mechanism (for ordering data)

Other ideas that are of use while designing a search engine:

• Mapping
• Clustering
• Wisdom of crowd for
  • Relevance scoring
  • Spam filtering
  • Suggestion Engine
• Natural Language Processing for
  • Query formation
  • Intent determination
  • One box searching - G****E like!

There's a lot more that could be of use, but lets start off with this for the moment!
