Hi, I've got a table with many Values of the Type REAL. These are my metric distances or my pivots to my sentences. The table looks like this: ID INTEGER, distance1 REAL, distance2 REAL, distance3 REAL, distance4 REAL, ..., distance24 REAL The range of the Value is in between 0 and 1. So it looks like this 0.196 or 0.891 That my query WHERE value BETWEEN (distance1 - radius) AND (distance1 + radius) WHERE value BETWEEN (distance2 - radius) AND (distance2 + radius) WHERE value BETWEEN (distance3 - radius) AND (distance3 + radius) WHERE value BETWEEN (distance4 - radius) AND (distance4 + radius) ... Now I'm searching for a suitable index. Does any of you have an idea? TX very much for any support! Janek Sendrowski
