• N collections per transaction
• complex clauses in insert/update statements
• N keys in $jsonSchema
• complex expression as an argument in any MQL position that takes an argument
• complex document with N keys / N levels of nesting in any MQL position that takes a document as an argument
• find({ "price": {A:{B:{"c":"d"}}}}).explain(); causes the nested document to end up in the `indexBounds`
