Jianfeng Jia commented on ASTERIXDB-1300:
-----------------------------------------

Then I don't get the idea of this issue.  Any example? 
I was thinking the intersection will choose all the indexes, by adding the /* 
+skip-index */ statement we can remove certain index access path, then it 
serves the purpose of choosing one or multiple desired indexes.
