What do you mean exactly?

Again, I don't understand what you mean.

>>> f = new OpenLayers.Filter.Comparison({type: OpenLayers.Filter.Comparison.LIKE, property: "foo", value: ".2"});
>>> f.evaluate({foo: "1"})
false
>>> f.evaluate({foo: "22"})
true
>>> f.evaluate({foo: "12"})
true
>>> f.evaluate({foo: "2"})
false

It looks good to me.

Could you please provide an example.

What would you expect? From the Filter Encoding specs: "The wildCard
character matches zero or more characters".
