As you may already know, direct database access is unsupported.
Through the API you can only do AND type searches. However you can manually
create an OR search through the API by making two searches and performing a
union on the results.
Here are the steps:
1. Do the first search. Ex. To="Bob"
2. Do the second search. Ex. From="Bob"
3. Combine the results from the 2 searches.
4. Remove any duplicates.
