The index analysis module acts as a configurable registry of Analyzers
|
||
|
|
that can be used in order to both break indexed (analyzed) fields when a
|
||
|
|
document is indexed and process query strings. It maps to the Lucene
|
||
|
|
`Analyzer`.
|
||
|
|
|
||
|
|
Analyzers are (generally) composed of a single `Tokenizer` and zero or
|
||
|
|
more `TokenFilters`. A set of `CharFilters` can be associated with an
|
||
|
|
analyzer to process the characters prior to other analysis steps. The
|
||
|
|
analysis module allows one to register `TokenFilters`, `Tokenizers` and
|
||
|
|
`Analyzers` under logical names that can then be referenced either in
|
||
|
|
mapping definitions or in certain APIs. The Analysis module
|
||
|
|
automatically registers (*if not explicitly defined*) built in
|
||
|
|
analyzers, token filters, and tokenizers.
|
||
|
|
|
||
|
|
See <<analysis>> for configuration details.
