CREATE ANALYZER speifies a whole analyzer chain for use in fulltext searches. It is possible to extend an existing analyzer or define a new analyzer chain from scratch. For examples and detailed explanation see Create a Custom Analyzer.

tokenizer_parameter:A name of a parameter for a given tokenizer.
token_filter_name:The name of a builtin token filter to be used.
token_filter_parameter:A name of a parameter for a given token filter.
