Performs a lexical search on a Milvus collection. The processor can query Milvus either by a list of IDs or by a filter. The IDs can be specified in a comma separated list in a specified attribute or in the content of the FlowFile. If the IDs are extracted from the content, the FlowFile should be in JSON format having an array of Milvus element objects. The JSON format is either the format of the output of the VectorQueryMilvus processor (list of lists) or a simple JSON list of Milvus objects. Each Milvus object is expected to have at least the primary key field specified.

|---|---|---|---|
| Query Mode | Query Mode | ID | Specify to query the Milvus collection either by ID list or by a filter. |
| ID Source | ID Source | Content | If the query mode is ID, the source of the IDs to query in Milvus. The source can be either an attribute containing the comma separated list of IDs specified in the ID Field Name property or the content of the FlowFile which should be in JSON format containing the list of Milvus elements.
