Reviewer filter in OJS 3.1.0.1

Hi all,

my question is: can you filter the reviewer list by more than one non consecutive keyword?
i.e.: I filter for ‘seed biology’ but only get reviewers with this exact constellation, but would not get a reviewer with “seed physiology and biology”
Boolean operators between two filter words like “seed AND biology” do not seem to work. When I search for “seed, biology” I don’t get any hit.
How is this seach function working?

All the best,
Heike
