Elasticsearch - tokenize terms by capitalized character, for example "TheStarTech" => [The, Star, Tech]

Question

Does Elasticsearch support tokenizer to tokenize terms by capitalized character, for example: Tokenize TheStarTech to terms [The, Star, Tech]. Pattern tokenizer seems helpful, any suggestions?

Answer 1

See this: World Delimited Token Filter

It does what you want and more. You can pass in the parameters as may fit your need. Check split_on_case_change parameter which is true by default.
