Creating query to gather team defects by project

[Eric]

Trying to create a query to gather defects create by project. I have this query so far; 

"Epic Link" = "REQx, REQx, REQx, REQx" AND issuetype = Bug AND created >= 2019-04-01 AND created <= 2019-06-04

But the query does not run at all unless I use only one req at a time, which is what I wouldn't like. Does anyone know any helpful queries. 

Thanks

Try something like this:

"Epic Link" in ( REQx, REQx, REQx, REQx ) AND issuetype = Bug AND created >= 2019-04-01 AND created <= 2019-06-04

 The "=" operator expects a single value.

But you mention by project. So maybe get rid of the epic links stuff all together and replace with 

project = my project
