How to put multiple conditions on a field, using Views 3? I am trying to make multiple conditions on a field in Views.

I found Views Conditional that allows only one condition.

I also found Views Custom Conditions, which I still don't really find how to use (very few documentation and the one left is very confusing to me). 

So I'd like to find out How to put multiple conditions on one field, using Views 3.
Consider module Views Contextual Filters OR (which only has a dev version today). Excerpt from its project page:


  ... provides a views plugin which modify query to support OR conditions for contextual filters.


A few issues on Drupal.org that may be of some help:


Using OR in filters breaks contextual filters.
Views AND/OR Contextual filters two ways.
