What does GET put_index_name_here/_settings show you?
I'm not on ES 6 yet but had the same issue lately and increased the limit to 1500
This is what I see now
{
" put_index_name_here": {
"settings": {
"index": {
"mapping": {
"total_fields": {
"limit": "1500"
...
For some reason that will not format...
Anyway, you can't change that on an existing index (at least in ES5) so I create our daily indices in advance to set these settings. I hope to have a more elegant solution when jumping to ES6 but it kind of works for now
