Simple analyzer

Simple analyzer

The simple analyzer breaks text into tokens at any non-letter character, such as numbers, spaces, hyphens and apostrophes, discards non-letter characters, and changes uppercase to lowercase.

Example

resp = client.indices.analyze(
    analyzer="simple",
    text="The 2 QUICK Brown-Foxes jumped over the lazy dog's bone.",
)
print(resp)

response = client.indices.analyze(
  body: {
    analyzer: 'simple',
    text: "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone."
  }
)
puts response

const response = await client.indices.analyze({
  analyzer: "simple",
  text: "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone.",
});
console.log(response);

POST _analyze
{
  "analyzer": "simple",
  "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone."
}

The simple analyzer parses the sentence and produces the following tokens:

[ the, quick, brown, foxes, jumped, over, the, lazy, dog, s, bone ]

Definition

The simple analyzer is defined by one tokenizer:

Tokenizer

• Lowercase Tokenizer

Customize

To customize the simple analyzer, duplicate it to create the basis for a custom analyzer. This custom analyzer can be modified as required, usually by adding token filters.

resp = client.indices.create(
    index="my-index-000001",
    settings={
        "analysis": {
            "analyzer": {
                "my_custom_simple_analyzer": {
                    "tokenizer": "lowercase",
                    "filter": []
                }
            }
        }
    },
)
print(resp)

response = client.indices.create(
  index: 'my-index-000001',
  body: {
    settings: {
      analysis: {
        analyzer: {
          my_custom_simple_analyzer: {
            tokenizer: 'lowercase',
            filter: []
          }
        }
      }
    }
  }
)
puts response

const response = await client.indices.create({
  index: "my-index-000001",
  settings: {
    analysis: {
      analyzer: {
        my_custom_simple_analyzer: {
          tokenizer: "lowercase",
          filter: [],
        },
      },
    },
  },
});
console.log(response);
