How to check all multiple keyword should be present in given text or not

Question

I am bit stuck with this how do I check all keyword should exist in my text

If any one keyword is not present then it should return me status : 1 or else 0

keyword='CAP\|BALL\|BAT\|CRICKET'

echo "HE AS CAP AND LOVE TO PLAY BALL BAT , ITS IS CALLED CRICKET" 

My code :

echo "HE AS CAP AND LOVE TO PLAY BALL BAT , ITS IS CALLED CRICKET" | grep -w "$keyword"
echo $?

Here is another way to achieve this using shell and grep:

diffSets() {
   [[ -n $2 && -z $( grep -vxFf <(echo "${1// /$'\n'}") <(echo "${2//|/$'\n'}") ) ]]
}

This function first replaces all spaces with newlines in first set and replaces all pipes with newlines in second set. Then it uses process substitution with grep -vxFf to get not-matching text from second set using first set as search patterns.

Testing:

keyword='CAP|BALL|BAT|CRICKET'
s="HE AS CAP AND LOVE TO PLAY BALL BAT , ITS IS CALLED CRICKET"

diffSets "$s" "$keyword" && echo "all" || echo "not all"
all

keywork='CAP|BALL|BAT|CRICKET|FOO'
diffSets "$s" "$keywork" && echo "all" || echo "not all"
not all

diffSets "$s" "" && echo "all" || echo "not all"
not all
