The whitespace analyzer

A whitespace analyzer breaks the text into terms when it encounters whitespace characters:

POST _analyze {    "analyzer": "whitespace",    "text": "This is my first program and these are my first 5 lines."}

This will result in the following terms:

[this, is, my, first, program, and, these, are, my, first, 5, lines]

This analyzer cannot be configured. To alter it, users must create a custom analyzer that mimics the whitespace analyzer, and then add filters to it. As you can see in the following expression, we can add filters to the analyzer:

PUT whitespace_example {    "settings": {        "analysis": {            "analyzer": {                "rebuilt_simple": {                    "tokenizer": "whitespace",                    "filter": [--add filter tokens here]                }            }        }    }}
