Dataset search

Purpose

Search for given term in a dso field, mode, and set.

Synopsis

out = search(dso_in,fieldname,fieldmode,fieldset,searchterm)

Description

Return 'out' as index of matches. Searches are case insensitive (use "" for case sensitive).

NOTE: If field is numeric then 'searchterm' will be interpreted as numeric expression. First characters can be relational operators.

Search Criteria (TEXT):

* = wildcard (similar to SQL wildcard, not strict RE)

"" = exact match.

re: = regular expression.

si: = sample index.

load arch

arch.label{2}
ans =
Fe
