=== Custom Analyzer
An analyzer of type `custom` that allows to combine a `Tokenizer` with
zero or more `Token Filters`, and zero or more `Char Filters`. The
custom analyzer accepts a logical/registered name of the tokenizer to
use, and a list of logical/registered names of token filters.
The following are settings that can be set for a `custom` analyzer type:
[cols="<,<",options="header",]
|=======================================================================
|Setting |Description
|`tokenizer` |The logical / registered name of the tokenizer to use.
|`filter` |An optional list of logical / registered name of token
filters.
|`char_filter` |An optional list of logical / registered name of char
filters.
