Description |

type |
Input |
Feature search scenario type. |
|
searchInput |
Input |
Pointer to the search input information. Call aclfvCreateSearchInput to create data of the aclfvSearchInput type in advance. |
|
searchRst |
Output |
Pointer to the search output result. Call aclfvCreateSearchResult to create data of the aclfvSearchResult type in advance. The queryCnt argument must be the same as that of searchInput. The number of returned search results is specified by the topk argument passed to the aclfvCreateSearchInput call and is also related to the topk argument passed to the aclfvInit call for initialization. If the topk argument passed to the aclfvCreateSearchInput call is greater than or equal to that passed to the aclfvInit call, the number of returned search results is determined by the topk argument passed to the aclfvInit call; otherwise, the number of returned search results is determined by the topk argument passed to the aclfvCreateSearchInput call. |
Returns
0 on success; else, failure. For details, see aclError.
Restrictions
- In N:M mode, multithreaded adding, search, or deletion is not allowed.
- In 1:N or N:M mode, if no repository is added, zero results are returned by the aclfvSearch call.
- This API call automatically creates a stream for synchronous task execution within the API. When the tasks are complete, the stream is automatically destroyed.
Hardware has restrictions on the total number of streams. For details, see aclrtCreateStream.
