Hmm.. interesting.
If (and only if) the records stored in "column" column have fixed
length (say, all are 50 characters in length) you could create and index
on, say, substring(column,45,50), and use this in the WHERE clauses in
your queries.
Or if the length of those records is not the same maybe it is
feasible to create an ondex on substring(column, length(column)-5,
length(column)).
