Configuring built-in analyzers

Serverless Stack

The built-in analyzers can be used directly without any configuration. Some of them, however, support configuration options to alter their behavior. For instance, the standard analyzer can be configured to support a list of stop words:

  PUT my-index-000001 { "settings": { "analysis": { "analyzer": { "std_english": { "type": "standard", "stopwords": "_english_" } } } }, "mappings": { "properties": { "my_text": { "type": "text", "analyzer": "standard", "fields": { "english": { "type": "text", "analyzer": "std_english" } } } } } } POST my-index-000001/_analyze { "field": "my_text", "text": "The old brown cow" } POST my-index-000001/_analyze { "field": "my_text.english", "text": "The old brown cow" }  

We define the std_english analyzer to be based on the standard analyzer, but configured to remove the pre-defined list of English stopwords.
The my_text field uses the standard analyzer directly, without any configuration. No stop words will be removed from this field. The resulting terms are: [ the, old, brown, cow ]
The my_text.english field uses the std_english analyzer, so English stop words will be removed. The resulting terms are: [ old, brown, cow ]
