Thanks David- I'll try the EntityWhereString first... I hope it works. I'd like to begin to fill the CMS system with textual data from service calls, blogs etc. Full text searches are going to be must for me.

This does sound like a special case where direct JDBC is the way to go. That just means you'll have some development to do as you can't use the tricks in the entity engine. And yes, that will require some technical effort to get the pieces tied together and there is no best practice or magic way to do it, so you'll just to buckle down and build whatever is needed. You might try the EntityWhereString as a last resort before directly using JDBC. That takes a free form string that goes into the where clause. -David Richard Fleming wrote: > David - > > Maybe you can help me... > > I need to query the products table and return 20 or so possible product ids > from the following customer input - "I need a maytag belt set for my maytag > washer" The columns involved in the query are productid, internal_name, > brand_name, description, long_description.
