Can a search be limited to specific columns of data within a record - say the first 100 bytes or some such thing?

Question

I am searching test data files columnar in nature and I need to limit the search to specific columns or a range of bytes within the records, like the first 100 bytes or columns 20 through 540.

Answer 1

You can't specify specific characters or columns but you can specify lines, for example to search through the first 10 lines for the word London:

Containing Text: LINES:0-10 London
