I am converting from .NET to Java and the following .NET Regular expression fails.
(?<before>.{0,10})" + mSearchTerm + "(?<after>.{0,255})
There are 2 named groups here, but the named part is not important to me.

The named groups are the only thing I see that won't work in Java, but you seem to have left off some quotation marks. Try this:
Pattern p = Pattern.compile("(.{0,10})" + mSearchTerm + "(.{0,255})");

May be there are more chars than the op want to catch before the first and after the last quote
In addition to the answer given by Alan Moore, the upcoming jdk7 will support named groups in regular expressions. See http://download-llnw.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html for details.
Also, if you are building a regex from a searchstring that is not a regex itself, it would be better to use Pattern.quote(searchString), so that all special characters are properly escaped.
