1. Adding analyzer to existing index

using settings api

PUT /analyzer_test/_settings
{
    "analysis" : {
        "analyzer" : {
            "my_second_analyzer" : {
                (... analyzer settings ...)
            }
        }
    }
}

error will occur stating that non-dynamic settings for open indexes cannot be updated

1-1. open & close index

open index : available for indexing and search requests

close index : refuse requests

1-2. dynamic & static settings

Dynamic settings : can be changed without closing the index

Static settings : require index to be closed

analysis settings are static settings, to change static settings,

first close index with close API

then change settings

reopen index with open API

POST /analyzer_test/_close

PUT /analyzer_test/_settings
{
    "analysis" : {
        "analyzer" : {
            "my_second_analyzer" : {
                (... analyzer settings ...)
            }
        }
    }
}

POST /analyzer_test/_open

1-3. static settings on production env

for mission critical production systems

create new index with updated settings

use index alias for the transition

2. Updating analyzer in existing index

to update analyzers, PUT request full settings with the same analyzer name

there will be conflict between docs index before the analyzer update and after

use update by query API to reindex

POST analyzer_test/_update_by_query?conflicts=proceed
