Beef Needed: I need to beef up my search please

I want to search for ἐπιεικής or ἐπιεικὲς within entries for Php 4:5 in a collection of commentaries.  How can improve this search, which I suspect is missing a lot:  <Bible~php4:5> AND (ἐπιεικής,ἐπιεικὲς). I am looking for commentary on language/usage of ἐπιεικής or ἐπιεικὲς.  

Thanks!

Note:  <Bible~php4:5> AND (ἐπιεικής,ἐπιεικὲς,moderation,reasonableness,considerate,modesty,gentleness,forbearance) produces too many unwanted results.
