elasticsearch中关键字类型的最大长度是多少？

Question

Here是关于关键字的文档，但它们没有任何限制。我发现的故障长度是256个字符但是如何获得关键字数据类型的最大长度？

Answer 1

最大字节数最多为32766.当字节数超过32766时，您将收到以下错误原因。

"reason": "Document contains at least one immense term in field=\"tags\" (whose UTF8 encoding is longer than the max length 32766), all of which were skipped.  Please correct the analyzer to not produce such terms.  The prefix of the first immense term is: '[82, 83, 75, 66, 99, 81, 87, 70, 69, 72, 49, 65, 70, 71, 48, 48, 53, 101, 86, 54, 112, 67, 53, 54, 80, 112, 56, 54, 70, 72]...', original message: bytes can be at most 32766 in length; got 32770",
"caused_by": {
  "type": "max_bytes_length_exceeded_exception",
  "reason": "bytes can be at most 32766 in length; got 32770"
