When inserting the document you can specify your own id for a document by using the field name "_id".
For specifying your own vector use the suffix (ends with) **"\_vector\_"** for the field name.
e.g. "product_description_vector_"
If inserting many items in a short timespan, use bulkInsert, or set update_schema to false.
Every insert api call temporarily locks and updates the schema, so will slow down with many inserts in quick succession.
