I am using Eclipse IDE , i need to search a String inside my Project .
So inside Eclipse , I clikced Search Item from Menu and Selected File and entered a String “exch” .
It is displaying all the results such as “exchange” , but i want to display only the Exact String matched “exch”

Check the “Regular expression” checkbox, and surround your word with
\bat the beginning and end which matches beginning and end (boundaries) of a word, so your search term will be\bexch\b
