Case insensitive path in match query

[Jogi_Michal (Jogi Michał)]

Hi folks,

I have a problem with case sensitivity in field path...

My mapping is dynamic:

 ...
 "http_headers": {
   "dynamic": true,
   "properties": {
     "content-length": {
       "type": "long"
     }
   },
   ...

so I have in there documents with fields with different cases:

[...].http_headers.User-Agent
[...].http_headers.User-agent
[...].http_headers.user-agent

My question is if there is a way of searching (match query) by the lowercase one and get results for all of them? Is there a possibility to search by case insensitive field path?

Thanks in advance,
Cheers
