Vault now supports a new type of extraction called Aggregation. This means that Vault will use multiple, independent sections of document to answer questions. Aggregation is useful for "list all X" queries or open ended questions "E.g. What is the effective date?" when the answer can be inferred from multiple independent sections (e.g. definition, signatures and date of last signature).
Aggregation is available for all tags. To set a tag as an aggregation, simply enable the aggregation tag when you create it.
The answer will then have the aggregation symbol in the Vault tag card:
Aggregation tags can be created for default, custom and vault team tags.
