Re: How to do a keyword search of a column without doing a table scan?

The context option is most likely your best bet. We did something similar with a web application and just dumped that column (and it's corresponding primary key) into a shared segment in memory and did an in-memory search and then hit the database again. Not the most preferred approach, but you have to do what you have to do.
