If you are asking about the regular expression feature of the Find/Replace dialog, you can find a lot of help in the Javadocs for the java.util.regex package.

If are trying to enter a regular expression in the dialog itself, you can hold down the CTRL key and press the spacebar key. That pops up suggested options and their uses.

And in case you are looking to have a functionality wherein you can test your own regular expressions, I think, default eclipse installation doesn't come with it, you may add 'plugins' to get such special features.
