Performs a filtered search over notes using a POST request. This endpoint supports the same filtering capabilities as GET /v2/notes, but allows more complex filtering through relationships.

Filtering by owner or creator email requires the members:pii:read scope.

Filter Logic

• Multiple values within a filter use OR logic (e.g., customer with id1 OR id2)
• Different filter types use AND logic (e.g., customer AND link filters)

Relationships

Filter notes by their relationships to customers (users or companies) and links (features):

• filter.relationships.customer[].id - Filter by customer or company UUIDs (OR logic within)
• filter.relationships.link[].id - Filter by linked feature UUIDs (OR logic within)
