Data Groups for dummies

I believe the issue Aaron's outlining above, whether intentionally or not, is one major way in which class match and class search differ: order of operands.

class match [< options >] < item > < operator > < class >class search [< options >] < class > < operator > < item >Note that in the above the  and  positions are switched. This indicates an implicit difference in the way the lookup is performed. This is further outlined in the examples in the wiki: 

* Example:

o class match [HTTP::uri] ends_with image_class

o read as, does the URI end with an element from image_class.

vs

* Example:

o class search blocked_paths starts_with [HTTP::uri]

o read as, does blocked_paths contain an element that starts with the URI.

Note that in the search, you're searching the class for something that starts with the string, rather than comparing the string to each to see if it matches (or starts with) one of the contained class entries. This is a very important difference depending on circumstances.

Hopefully that makes sense. üòâ
