Lowercase tokenizer
editLowercase tokenizer
editThe lowercase
tokenizer, like the
letter
tokenizer breaks text into terms
whenever it encounters a character which is not a letter, but it also
lowercases all terms. It is functionally equivalent to the
letter
tokenizer combined with the
lowercase
token filter, but is more
efficient as it performs both steps in a single pass.
Example output
editresp = client.indices.analyze( tokenizer="lowercase", text="The 2 QUICK Brown-Foxes jumped over the lazy dog's bone.", ) print(resp)
response = client.indices.analyze( body: { tokenizer: 'lowercase', text: "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone." } ) puts response
const response = await client.indices.analyze({ tokenizer: "lowercase", text: "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone.", }); console.log(response);
POST _analyze { "tokenizer": "lowercase", "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone." }
The above sentence would produce the following terms:
[ the, quick, brown, foxes, jumped, over, the, lazy, dog, s, bone ]
Configuration
editThe lowercase
tokenizer is not configurable.
