Search using regular expressions

Asked by jonas nissen on 2013-07-11

Can you give an example on how to use regular expressions for filtering / searching? I have used regular expressions before, but i cannot quite get it to work. I see a message "This is an invalid regular expression ...".

Just a simple example to clearify if there is some special way to use it. Thanks :-)

Short version: some characters (., *, ?, +, some others) have special meaning. For instance a character followed by a "*" means any number of occurences of this character so a* matches "", "a", "aa", "aaa", etc. "+" means at least one occurence; "?" means 0 or 1 occurence, so those three must follow another character. "." is a wildcard meaning any character.

Can you help with this problem?
