Hi All,
I would like to use not\_analyzed along with lower-case tokenizer. So that,
tokens of not analyzed field will store in lower-case.
is it possible to do above thing?
Regards,
Ankit

Hi Ankit,
Setting a field to not\_analyzed instructs ES to not change anything. What
you need is analyzed with a custom text processing. You can combine the
keyword tokenizer
([Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/index-modules/analysis/keyword-tokenizer/)
) with the lowercase token filter
( [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/index-modules/analysis/lowercase-tokenfilter/)
)
You need to define a custom analyzer during index creation
( [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/index-modules/analysis/custom-analyzer/)
) and then refer to it in your mapping (using the analyzer setting on the
field in question)
Cheers,
Boaz
