Hello Minas, thanks for your sample... Trying around a lot and wondering why your sample does work and mine did not, I finally found out, that the reason is, when indexing over more than one field, the fields being index *must* be subsequent. So inserting a FieldDef between Id and Remark in your sample will result in the same exception I described. Is this always the case or is this specific for the data-base type, i.e. Paradox. Or is there a way to allow non-subsequent fields being indexed too? Thanks, Michael
