Hi,

I am using elasticsearch for last 6 months. I am very happy to work with
elasticsearch till now.

But I have the following requirement:
I have the Japanese data. I want to create index on Japanese data. And also
I want to search on indexed japanese data.

I did lot of google search, but I am not getting the proper guidance/link.

Hi,

I want to create index on Japanese data.

Where's your data? In csv files, mysql?

And also I want to search on indexed japanese data.

If you want a japanese analyzer, you can try elasticsearch-analysis-kuromoji

My data is available in MSSQL database. I am able to read the japan data
and create the index using java. Here I followed the same approach which I
followed for creating the english data earlier. Am I doing in the right way?

In this case, will the default analyzer be applied automatically for Japan
data also?.

Thanks,
Samanth

You can visit "localhost:9200/${your_index}/${your_type}/_search" in your
browser.
Then check whether the number of hits._total is correspond to the number of
your db data or not.

Yes, ES will use standard analyzer when no analyzer is specified explicitly
in your _mapping or elasticsearch.yml.

Actually I think kuromoji is better than the default standard analyzer if
you want to search the japanese fields.

You can try curl 'localhost:9200/_analyze?analyzer=standard' -d ' 高速スケーラブル検索エンジン' and change the 'analyzer' to 'kuromoji' to check which one
is better if you're interested.
