Lowercase tokenizeredit
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 outputedit
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 ]
Configurationedit
The lowercase
tokenizer is not configurable.
