Query filtering with Objectify

Question

I have a problem that I need to filter query result with Objectify. Typically here is what the String @Key field on stored entities would look like:

Now I want to do a query filter like this for the @Key field:

uid:j*:points

Where, I am expecting to get the first three (3) entities listed above. Is this possible with Objectify?

are you looking for a LIKE query ? http://code.google.com/p/objectify-appengine/wiki/FrequentlyAskedQuestions#How_do_I_do_a_like_query_(LIKE_"foo%") , maybe something similar to this 1 `String start = "uid:j"; ... = ofy.query(MyEntity.class).filter("field >=", start).filter("field <", start + "\uFFFD:points");` — Daniel, Aug 28 '12 at 07:36

As described before, you can do this, but only if you compare start of the string: uid:j*

ofy.query(EntityClass.class).filter("property >=", "uid:j")
                            .filter("property <", "uid:j" + "\ufffd");

You mean this will not work: ofy.query(MyEntity.class).filter("field >=", start).filter("field <", start + "\uFFFD:points"); ? – quarks Aug 28 '12 at 15:46
