So far my best idea is to create a tsvector column containing both

I am pretty new to text search, so I'd welcome any suggestions.

create your dictionary, which index R0001234 as R0001234 and R1234
Seems, dict_regex is your friend.

Nice - I was thinking something like that would be useful, but Googling hadn't found me anything. Thanks for that link Oleg.

Wouldn't it be more efficient to have the regex-dictionary map just to R1234 though? Or R0001234, I suppose.
