question: public boolean addStrictCompare ( String keyProperty , ExprIdentNode keyPropNode , ExprIdentNode indexPropertyIdent ) { QueryGraphValueDesc value = findIdentEntry ( indexPropertyIdent ) ; if ( value != null && value . getEntry ( ) instanceof QueryGraphValueEntryHashKeyedExpr ) { QueryGraphValueEntryHashKeyedExpr expr = ( QueryGraphValueEntryHashKeyedExpr ) value . getEntry ( ) ; if ( expr . isConstant ( ) ) { return false ; } } if ( value != null && value . getEntry ( ) instanceof QueryGraphValueEntryHashKeyedProp ) { return false ; } items . add ( new QueryGraphValueDesc ( new ExprNode [ ] { indexPropertyIdent } , new QueryGraphValueEntryHashKeyedProp ( keyPropNode , keyProperty ) ) ) ; return true ; }
target:  Add key and index property.
