I was just doing a quick search and came across a fairly specific and unfortunate limitation of the search function.

I searched for 'Contains: Ape' and realised it (and similar search options) could probably do with a third option to search for the specific term, rather than including it as part of a larger word. Searching for 'Ape' brought up Spellshaper and Shapeshifter cards as well as the simians I was hoping for. A slightly awkward side effect was that one of the top options, alphabetically, was Alex, Zephyr Mage, which gave me a bit of a "wtf?" moment given the search term!
