Local searches are performed in your NAT32 HTM directory and are executed by the Tcl script search. All files with the extension htm or HTM are searched. The search string must be a regular expression.

Here are a few examples:

"My search string" Multiword search strings must be quoted
"Port map*" '*' matches zero or more characters
"set?" '?' matches any single character
"pmap | ipmap" '|' logical OR
"[pP]map" Matches pmap or Pmap
