You can also extract a fragment of a string using the substring function -

var text = "azerty uiop hello qsdf ghjklm wxcvbn";
var target = text.indexOf("hello");
print(text.substring(target-5,target+10));

This should work:

var text = "azerty uiop hello qsdf ghjklm wxcvbn";
console.log((text.match(/.{0,5}hello.{0,5}/) || [''])[0]); // uiop hello qsdf

var text = "azerty uiop hello qsdf ghjklm wxcvbn";
text.match(/.{5}hello.{5}/)[0]; // uiop hello qsdf

Try using a regex in plain javascript:

/.{5}hello.{5}/.exec(text)
