When searching for "fin", "dorsal fin fold" appears before "fin" in the ZFA ontology

[arteymix]

The results are correct, here's the hierarchy for "dorsal fin fold":

• zebrafish anatomical entity
• anatomical structure
• multi-tissue structure

and for fin:

• zebrafish anatomical entity
• anatomical structure
• organism subdivision
• surface structure
• fin

The algorithm visits "dorsal fin fold" first and there is no particular relationship between the two terms.

I can't seem to find any relationship to include that would establish the order we want.

It might make little sense to use the depth when two terms are not topologically related. We'd probably be better off relying on the full-text similarity.
