I've had a look into this again, I think I got misled looking at this one:
// pattern based "like" filter
filter = ff.like(ff.property("code"), "2300%");
// you can customise the wildcard characters used
filter = ff.like(ff.property("code"), "2300?", "*", "?", "\\");

I'm reading data from a KML file into MemoryStore. I think the problem
lies in that I'm using the "description" property and this has some '\n'
characters which confuses things. The following works, but not on my
description property:
filterFactory.like(filterFactory.property("name"), "*56*");
