Hi,
I have this
Pattern pattern = Pattern.compile(wordToSearch.toUpperCase());
Matcher matcher = pattern.matcher(singleWord.toUpperCase());
but if the String wordToSearch contains a ( I receive an java.util.regex.PatternSyntaxException: Unclosed group near index...
How to escape this characteres?
thanks in advance,

The OP is obviously just trying to match the search term literally, not as a regex, but converting it or the search target to uppercase is still wrong. @OP, if you're working with JDK 1.5 or later, do this: Pattern pattern = Pattern.compile(Pattern.quote(wordToSearch),
Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(singleWord);
If you're still on 1.4, you can quote it manually, as Sabre suggested:Pattern pattern = Pattern.compile("\\Q" + wordToSearch + "\\E",
Pattern.CASE_INSENSITIVE);
