Retrieve all MongoDB documents that match multiple regular expressions

I'm looking to search a database for documents that match multiple regex terms in one field and also match another list of regex terms in a different field.

For example:

    .find({
      fieldA: { $regex: /stringA/i } OR 
      fieldA: { $regex: /stringB/i } AND
      fieldB: { $regex: /stringC/i } OR
      fieldB: { $regex: /stringD/i },
    })

Currently, I have the following query, which locates results matching all regex terms:

    .find({
      fieldA: { $regex: /termA/i },
      fieldA: { $regex: /termB/i },
      fieldB: { $regex: /termC/i },
      fieldB: { $regex: /termD/i },
    })

Thank you in advance!
