Search for very specific pattern with less

Hi,

I want to search a certain pattern with less command in a files. For examples, I have a files with this entry:

POLAR xx
POLARX xc
POLARXI x1
POLARZZZY vb
POLARLLLLLLL ee
POLARIIIIISSSSSID xx

I want to search for the lines, which only contains 'POLAR' pattern. If I use the usual '/ (pattern)' command, it would show all entry in the files. I know, if I use the 'grep -P "\t(pattern)\t" ' command, it would give only the first line. However, could I use the same method in 'less'? or is there any other way?
Thank's

Tcl_StringMatch(3)					      Tcl Library Procedures						Tcl_StringMatch(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern SYNOPSIS
#include <tcl.h> int Tcl_StringMatch(str, pattern) int Tcl_StringCaseMatch(str, pattern, flags) ARGUMENTS
const char *str (in) String to test. const char *pattern (in) Pattern to match against string. May contain special characters from the set *?[]. int flags (in) OR-ed combination of match flags, currently only TCL_MATCH_NOCASE. 0 specifies a case-sensitive search. _________________________________________________________________ DESCRIPTION
This utility procedure determines whether a string matches a given pattern. If it does, then Tcl_StringMatch returns 1. Otherwise Tcl_StringMatch returns 0. The algorithm used for matching is the same algorithm used in the string match Tcl command and is similar to the algorithm used by the C-shell for file name matching; see the Tcl manual entry for details. In Tcl_StringCaseMatch, the algorithm is the same, but you have the option to make the matching case-insensitive. If you choose this (by passing TCL_MATCH_NOCASE), then the string and pattern are essentially matched in the lower case. KEYWORDS
match, pattern, string Tcl 8.5 Tcl_StringMatch(3)
