I just saw an outrageous example of the art of semantics in Search Suggestions.
I typed in [kw1 kw2 with kw3] and one of the suggestions was [synonym1 kw2 without synonym3] - 3 out of 4 words were transformed, and yet the Suggestion was a really good query for what I was looking for.
I don't want to take this thread away from its main topic, so I started another thread
about the semantic changes at Google: Google's Semantic Processing Is Getting Very Savvy [webmasterworld.com]
Google is trying to let pages rank well for a variety of closely related phrases. Up until this year, best practice has been to create one page per phrase. Now it looks like you can somehow make a single page rank for multiple phrases.
I think its time to revisit ideas such as co-occurrence and phrase-based indexing. And also to walk away from the "one page per phrase" approach. I even wonder if "one page per phrase" might soon (or even already?) be the subject of some ranking demotions. It smells kind of like eHow, you know?
