1. As a new user, I think we may need to add a brief instruction on the top of the website. Otherwise, it's not that explicit why we need to enter two lists of concepts.
2. In the tip for "service", there is a duplicate "Association". We can also make "Frequencies" and "Association" bold.
3. I entered one concept to each query list. In the result, what does "LnRatio" mean? Do we need to add a tip for it?
4. I entered same concept lists (e.g., abnormality of the musculature, muscle weakness) to two search boxes and I didn't get any result. However, if I delete one of the concept from a list, 1 result is returned. Is that a bug or did I misunderstand the function we provided here?
5. When only 1 result is returned, should the hint be change to "1 result returned" instead of "1 Results returned"?
6. The curerent dataset instruction is not informative enough... I still don't know what dataset is for...
7. Not quite sure what's the unit of the "pair count"?
