For some reason that I can't determine, this works only from a command line, not from within the script. When run from a script, my search string (which I'm echoing so I can see the conversion) looks like this:
search string: '(this)'
output: \1this\1

From the script:
search_arg=`echo "$*" | tr -s ' '` #remove redundant spaces
search_arg=`echo "$search_arg" | sed 's/\([(.)]\)/\\\1/g'`
echo "$search_arg"

Tcl_Backslash(3)					      Tcl Library Procedures						  Tcl_Backslash(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_Backslash - parse a backslash sequence

SYNOPSIS

       #include <tcl.h>

       char
       Tcl_Backslash(src, countPtr)

ARGUMENTS

       char *src (in)		    Pointer to a string starting with a backslash.

       int *countPtr (out)	    If countPtr is not NULL, *countPtr gets filled in with number of characters in the backslash sequence, includ-
				    ing the backslash character.
_________________________________________________________________

DESCRIPTION

       The use of Tcl_Backslash is deprecated in favor of Tcl_UtfBackslash.

       This is a utility procedure provided for backwards compatibility with non-internationalized Tcl extensions.  It parses a backslash sequence
       and returns the low byte of the Unicode character corresponding to the sequence.  Tcl_Backslash modifies *countPtr to contain the number of
       characters in the backslash sequence.

       See the Tcl manual entry for information on the valid backslash sequences.  All of the sequences described in the Tcl manual entry are sup-
       ported by Tcl_Backslash.

SEE ALSO

       Tcl(n), Tcl_UtfBackslash(3)

KEYWORDS

       backslash, parse
