How to investigate query of Liferay

Enable slow query log with low threshold would be the easiest way.

1. Navigate to Sense http://localhost:5601/app/dev_tools#/console e.g.
2. Find index names at http://localhost:5601/app/management/data/index_management/indices.
3. Modify query below appropriately.

PUT /[index_name]/_settings
{
    "index.search.slowlog.threshold.query.warn": "0s",
    "index.search.slowlog.threshold.query.info": "0s",
    "index.search.slowlog.threshold.query.debug": "0s",
    "index.search.slowlog.threshold.query.trace": "0s",
    "index.search.slowlog.threshold.fetch.warn": "0s",
    "index.search.slowlog.threshold.fetch.info": "0s",
    "index.search.slowlog.threshold.fetch.debug": "0s",
    "index.search.slowlog.threshold.fetch.trace": "0s",
    "index.indexing.slowlog.threshold.index.warn": "0s",
    "index.indexing.slowlog.threshold.index.info": "0s",
    "index.indexing.slowlog.threshold.index.debug": "0s",
    "index.indexing.slowlog.threshold.index.trace": "0s",
    "index.indexing.slowlog.level": "trace",
    "index.indexing.slowlog.source": "1000"
}

3. Search / index and you'll see log files under ./es/logs you can also change ./es/config/elasticsearch.yml for above settings and run docker-compose up --build

Search from query to see how analyzer works.

1. Navigate to http://localhost:5601/app/dev_tools#/console
2. Paste query below

GET /[index_name]/_analyze
{
  "field": "title_ja_JP",
  "text":  "東京都清掃局"
}
