确保 Solr 已实际启动。默认情况下，Riak 2.x 中禁用搜索。为了启用它，将search/etc/riak/riak.conf 中的属性更改为on. 然后重启Riak。

我有类似的问题 RiakError: 'Unknown message code: 56'

我通过更改“riak.conf”文件中的搜索参数来解决它这是文件位置，如果您使用的是mac并通过brew安装

/usr/local/Cellar/riak/2.2.2/libexec/etc/riak.conf

这是我从关闭更改为打开的代码行

## To enable Search set this 'on'.
## 
## Default: off
## 
## Acceptable values:
##   - on or off
search = on

我发现文档解释有点难以理解，但或多或​​少是解决问题的参考。
