No result when using search API

[MissMakima 2]

curl -X 'GET' \
  'https://<Hostname>/emby/Items?SearchTerm=<Keyword>&IncludeItemTypes=Episode&api_key=<Key>' \
  -H 'accept: application/json'

And I got the result as below:

{
  "Items": [],
  "TotalRecordCount": 0
}

Meanwhile I did have matched records in my Emby Library.

If I do this on web interface or inside the client software, there would be "Items" but the "TotalRecordCount" is constantly 0, no matter how many "Items" are returned.

HI, currently if the search query length is less than 4 characters, then total record count is disabled for performance reasons.
