Add wildcats for Search

[poltrian]

Thanks again for your great work.

Could you please add wildcats? I try to find a receipt, but only the full name will find one. But i try to find any Cake, nothing is shown.

Thanks..

The search is based on keywords only at this point, so unless your recipe is tagged with "cake", it won't show up when searching for that.

Closing as fuzzy search is not something I have enough time for at the moment.

I just hacked something in PR #12. Maybe this can be useful here.

@christianlupus it seems to work well, so merging it
