A trigram index took 9 minutes to build but improved the regular query from 67 seconds down to 500 ms. Although this is an impressive improvement, I'm afraid that the index might create a delays in other parts of the application (INSERT / UPDATE). We will probably rework the design of this particular table. Thanks to everyone who helped me in this matter. Regards Klaus
