UNDERSTANDING THE QUERY
• Does the query have any known entities?
• Beyonce, Cristiano Ronaldo, Sydney Opera House
• Are there useful synonyms?
• Are the synonyms ambiguous? (gm = general motors, genetically
• What’s the context?
RETRIEVAL AND SCORING
• Send the query to all the shards
• Each shard then:
• Finds matching pages
• Computes a score (S1) for query+page
• Sends back the top N pages (by S1)
• Combines the top pages and then sorts (ranks) by score
POST RETRIEVAL ADJUSTMENTS
• Too much duplication in results?
• Negative user interactions?
• Search abandonment
• Need for spam demotions/manual actions?

but it shouldn't be there.)
• Is your sidebar or widgets content all the way at the top? Remember,
your most important links and content should be at the top of the
HTML. This is more important the bigger the site is.
