Searching on key segment in RMS indexed file?

» close window

The Question is:

 
Is it possible to search a rms file with a
segmented key using a substring
( not of the first key)
eg segmented key = surname + forename , and
search value(forename) = "John".

The Answer is :

 
  Unless the target segment is a unique key in its own right, you are
  limited to a sequential search on the entire keyspace...
