Semantic vector search over the AI embeddings of records within a chosen space. These endpoints require the space to have vectorSearchEnabled.

• similar — records most similar to a reference record or query.
• outliers — records that deviate most from the rest of the set.
• context — the surrounding records that give a record its context.

Results can be narrowed with either a filter expression or a segment_id. The two are mutually exclusive — supply at most one.
