File asterixdb/asterix-algebra/src/main/java/org/apache/asterix/optimizer/rules/RemoveUnusedOneToOneEquiJoinRule.java:

Line 187:         // Suppose we Project B over A.a ~= B.b and, where A.a involves a secondary
word index.
What does Project B mean? Project entire record? or just one or any fields is OK?


Line 192:         }
Can you explain this part?

Line 19: 
Can you a description of this test? What it is intended for? And the expected result?

An example: /apache-asterixdb/asterix-app/src/test/resources/runtimets/queries/index-join/btree-primary-equi-join/btree-primary-equi-join.1.ddl.aql
