      Description

      I've sent a mail to the user's mailing list, but didn't get any feedback from the development team.

      The mail was:
      ------------------------------------------------
      Hello all,

      I'm trying to do something like this:
      Iterable<NewsContent> newsIterable = from("n").in(news).where(ne("n.title", "thisworks").and(ne("n.title", "thisworks not"))).select("n");
      But it does not work since you can not have spaces in the string "thisworks not".
      Any solution for this?

      Another feature I miss a lot is the contains method from the String object.
      This is something really important for what I'm trying to achieve.
      Any idea how to do that?
      I don't mind dwelling into Quaere source code, but I would appreciate if someone can point me to the right direction.
      ------------------------------------------------

      We decided to improve this in the source code from the SVN trunk and now we can do something like:

      Iterable<NewsContent> newsIterable = from("n").in(news).where(notContains("n.getTitle()", "thisworks").and(contains("n.getTitle()", "thisworks not"))).select("n");

      This does not uses the contains method from String since it is case sensitive. We use a regex Pattern instead:

      Pattern.compile(Pattern.quote(rightHandSide), Pattern.CASE_INSENSITIVE).matcher(leftHandSide).find();

      You can found in attach a diff with the changes we have done in the source code.
      Do you think it is possible to add them to the trunk?

      Many Thanks,
      Samuel Santos
