There's nothing you can do about it, or even if you could, it wouldn't be worth the time and money.

You've learned a valuable lesson here. If you're going to spend time performing research and drafting up a specification in the detail you have done make it clear to the client you will charge them for this work. Also, take an upfront payment in order to mitigate any risks such as your client defaulting on the final payment, at least you cut your losses to a minimum this way.
