Guidance

• Every collection has a default _default partition.
• Partitions allow organizing data for more targeted searches.
• A partition must be loaded before it can be searched.
• Before dropping a partition, confirm with the user -- all data in it will be deleted.
• Use partition stats to check row counts per partition.
• For filter expression syntax used in vector operations on partitions, see the vector skill.
