How to search google scholar for singular and plural words?
If the alternative terms are part of a phrase, then you could use parentheses () and a vertical bar |, like &quot;the (woman|women)&quot;.
The same applies to, for instance: &quot;the (entrepreneur|entrepreneurs) told&quot;. I tested it and it works.

(EDIT: I originally wrote that the wildcard entrepreneur* should work, but my test was not so convincing. Thanks to lighthouse keeper's comment.)
