Currently, we have a simple Content Search web part which pulls data from ListA, but also want to pull data from ListB, so in this Content Search web part, the result will show data from ListA+ListB.
I did some research, it looks like feasible. I am new to SharePoint, not sure if this is the right approach. Right now we have this in the web part's query text:
contentclass:"STS_ListItem" ListID:"ListA ID"
I am guessing the combined query would be something like:
contentclass:"STS_ListItem" ListID:"ListA ID" OR ListID:"ListB ID"
Am I on the right track? Any suggestions?
