Text Search

Anders Pedersen discusses one method he used to implement fast text search in SQL Server:

Looking into what was needed, I quickly realized there was a LOT of data, guess 50+ years of news broadcasts will do this.  Consider this was in the early 2000s, some innovation was needed from anything I had coded before.  Obviously LIKE searches was out of the question, full text search was not available.  So what to do?

Basically I decided to break down each broadcast to words into a separate table, the entire application fit in 2 tables: Story and Words.

This is a case in which thinking about the grain of data helps solve an otherwise-intractable problem.
