is a possibility, though it might be clearer if you could give some more context. It seems a rather odd sentence, from what I know of relational databases. Queries should normally return everything asked for, without producing "exception lists of name supplements which should be rejected in a name search".

By the way, I see Leo gives "name affix" for Namenzusatz, but it strikes me as rather non-English, and looking at a Google search on the phrase only reinforces this impression.

I have just understood what it really says, and what it is doing. It is dealing with the problem that making a relational database search on a personal name field you can miss some entries you want to get, if they have titles such as \"Dr.\" in them. You search on \"Watson\", but it doesn´t give you a record that has \"Watson, Dr.\" in the name field.

The understanding makes more sense of \"name affixes\" but this still strikes me as rather odd, even though I see Fred agrees with it. I used to write stuff like this, descriptions of relational database systems, and I think I would have used either \"name extensions (titles etc.)\", or even just \"titles etc.\".
