Using analyzers based on language detection

Elastic Stack Elasticsearch
1

Hi,

I am using langdetect plugin to dynamically assign the analyzer at index
time.

PUT test
POST test/article/_mapping
{
"article" : {
"_analyzer" : {
"path" : "description.lang"
},
"properties" : {
"description" : { "type" : "langdetect" }
}
}
}

Langdetect plugin detects the language as 'en', 'fr', 'de', and so on. so
the analyzers should be defined as 'en', etc. This make them less
descriptive and the context of analyzer is lost. Is it possible to derive a
more descriptive name, such that _analyzer is resolve to 'en_icu_analyzer',
instead of just 'en'?

Something like... (this does not work), this is just what i want to
achieve.

article" : {
"_analyzer" : {
"path" : "description.lang" + "_icu_analyzer"
}

Another question - is it possible to define analyzer dynamically at field
level rather than at the index level?

Thanks,
Nitin

This requires a change in the langdetect plugin, feel free to open an issue
at

It should be trivial to wrap something like a String.format() around the
language name by config request.
