 to execute the retrieval.
Notes:
When the index configuration among multiple topics is inconsistent, the retrieval statement may report errors under some log topics. At this time, only the data and error information of log topics without error reporting are displayed. For example, Topic A has the field KeyA and enables the key-value index, but Topic B does not have this field. When using the retrieval statement KeyA:xxx to perform retrieval, Topic B execution will report an error, and only logs related to Topic A can be viewed.
