How to specify analyser to use

Elastic Stack Elasticsearch
1

Hi,

How can I:

  1.  check which analyser is used for my indexing – I have not specified

any when I indexed my documents.

  1.  specify which analyser is used for my indexing – I know the doc

specify at url
http://www.elasticsearch.org/guide/reference/index-modules/analysis/ the
sample configuration – but what is this configuration? – a text file? And
if it is where do I put it under elasticsearch root directory. If it is not
a config file what command do I use to specify which analyser I want to use?

Regards,
Janusz

By default, the standard analyzer is applied.
If you want to apply another one, you have to define a mapping.

See the Put Mapping API.

Here is an example: Test case for multifield fields · GitHub

Hi Dave,
Can I somehow see that it is standard analyzer - using some curl command?
Not that I don't trust you - I just would like to know the method to verify
it?

Yes.

Do

curl http://localhost:9200/index/type/_mapping?pretty

You will get your mapping. If no analyzer is defined, then standard is applied.

BTW, if you want to understand how Elasticsearch analyzed your data, have a look at the _analyze API. Very useful.
