In HTTP, it is up to the implementation to limit the request URI length, see

[http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2.1](http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2.1)

ES uses Netty for HTTP implementation, and current Netty HTTP request  
limits are documented here

[http://static.netty.io/3.5/api/org/jboss/netty/handler/codec/http/HttpRequestDecoder.html](http://static.netty.io/3.5/api/org/jboss/netty/handler/codec/http/HttpRequestDecoder.html)

Best regards,
