Extended search supports
all the basic GREP options: Expression searches, Case-sensitivity, whole word, and sub-directory searches, line
numbers and filenames only.
Extended Search is FAST. Much
faster than Delphi 3's Find in Files option, as fast as GREP from the command line. Search 75,000 lines of text
per second, the entire Delphi library source code in under 4 seconds (on a P133 with 32 megs RAM)
