I need to do exact string search on one of field in my documents
(preface you can see in my SO question ). So I probably need to
change index mapping for this field from the default to something what
doesn't try to process input string. But here I stuck.
I probably need to change analyzer type, used for particular field
with Put Mapping API , but I just can't find the right way to do
that. I fount an example, where the "not_analyzed" index was used for
a field (, the second snippet), but it's unclear was it created or
it is a default option?
Furthermore, Get Settings method  just fails for my index with the
message: "No handler found for uri [/records/_settings/] and method
[GET]". So I can't inspect current configuration state.
I'll appreciate any tips about how I can solve this issues.
