I have a Field search using  template with case number,  case number is defined as the first two numbers being the year of the document 14 for 2014,15 for 2015 etc...  with a dash and then numbered sequentially. Right now I am doing a search as follows with   yy-[0-9][0-9]   ex (14-[0-9][0-9], 15-[0-9][0-9]).

I would like to do a search on anything greater than the year 2014. Is there a way to do that or have a search where the case number  includes 14 ,15, 16,17 and 18  or  >14-[0-9][0-9]  so I could have all the years in one search?
