please help me to solve this problem .


Thank you for patience. Please check the following link with sample code which is related to your requirement.


Just update the following code, it will return only desired results. Hope, this helps.

Pattern regex = Pattern.compile("\\bhello\\b");
doc.getRange().replace(regex, "", options);

Pattern regex = Pattern.compile("\bhello\b");
this “\b” is not working in Linux server can you give me other solution.


Kindly share screenshot of the following portion of code, where it shows undesired behavior just for reference.

it’s not showing any error process stack in this line.


I hope you tried with the both, double slash “\\bhello\\b” and single slash “\bhello\b”. Hope, this will helps and also read the members of FindReplaceOptions class.

Please set the value of FindReplaceOptions.FindWholeWordsOnly property as true in your code. The true value indicates the oldValue must be a standalone word.
