Lowercase tokenizer [analysis-lowercase-tokenizer]
The 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 [_example_output_12]
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 [_configuration_13]
The lowercase tokenizer is not configurable.
