Explain Tokenizer in ElasticSearch.

1.	Explain Tokenizer in ElasticSearch.
Answer» When a tokenizer receives a STREAM of characters (text), it tokenizes them (usually by breaking them up into individual words or tokens), and OUTPUTS the stream of words/tokens. Elasticsearch COMES with several tokenizers that you can use to build your custom ANALYZERS. A whitespace tokenizer, for example, breaks text into individual tokens whenever it encounters any whitespace. The text "Scaler by InterviewBit!" would be converted into terms or tokens [Scaler, by, InterviewBit].
