[Samba] Spotlight with elasticsearch backend on OSX13

[Computerisms Corporation]

Hey All,

I have setup a samba fileserver in workgroup config with installed 
elasticsearch and fscrawler backend.
On my setup, the search function using OSX has been a little flaky, and 
does not return any results most of the time.
I have deployed the same setup on multiple fileservers with many 
combinations with no luck.
I went through the past emails in the mailing list and fixed a could 
things in the smb.conf and still unable to search reliably.

for eg. when I search on the "network" or "Shared", it returns some 
search results but when using the same search string on the mounted 
volume, I get no results.

my smb.conf
[global]
    workgroup = WORKGROUP
    log file = /var/log/samba/log.%m
    max log size = 1000
    logging = file

I am stuck and unable to move forward, does anyone have any suggestions?
Please let me know if you need logs too.
