How to search for a string and similar word in a text?

Question

I have to lookup for a word "age" and similar word in a text file.

I have following sentence :

• 18 years of age
• man aged 51
• man ages between 25 to 50
• between 5 to 75 years of age.(with dot)
• between 5 to 75 years of age, (with comma)
• agent name is xyz (agent contain age).

String.contains always return true in each case. My requirement is to pass the first five sentence and it return false in last case.

I will solve this problem by writing some code which contains a bunch of string " age ", " age." , "ages", "aged", " age," etc..

Is there any better way to solve this problem.

If you use regex, you have to put all the possiblities.

string.matches("(?i).*\\bage[ds]?\\b.*");
