An operator used to assert that two (or more) parts of a  or  must both be true.

Notes

• Conjunction can be represented by the AND operator. A conjunction of A with B, means that both A AND B must be true.
• Conjunction gives the same result as an intersection between the set of concepts or expressions for which A is true and the set of concepts or expressions for which B is true.

Example

• The following expression constraint is satisfied by clinical findings which are  of both  AND . 

  < 19829001 |Disorder of lung| AND < 301867009 |Edema of trunk|
