I am using below script and It should search for the string "Download"

Code:
#!/bin/bash
        search="Download"
        logfile=/home/kudos/hari/logfn.txt
        str_output=""
        start_year=2014
        start_month=02
        start_day=9
        end_year=2015
        end_month=03
        end_day=10
                while [ $start_year -lt $end_year ];do
                while [ $start_month -lt $end_month ];do
                while [ $start_day -lt $end_day ];do
                        str_output+="$(grep $start_year-$start_month-$start_day $logfile|grep $search && printf '\n' )"
                        ((start_day++))
                        [ $start_day -gt 31 ] && start_day=1 && ((start_month++))
                                done
                                ((start_month++))
                        [ $start_month -gt 12 ] && start_month=1 && ((start_year++))
                                done
                                ((start_year++))
                        [ $start_year -gt $(date +'%Y') ] && break
                                done

LOGSAVE(8)						      System Manager's Manual							LOGSAVE(8)

NAME
logsave - save the output of a command in a logfile SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ] DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will also be written to standard output. If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in logfile logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to /var/log. OPTIONS
-a This option will cause the output to be appended to logfile, instead of replacing its current contents. -s This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console, while not being written to the log file. -v This option will make logsave to be more verbose in its output to the user.
