PluginTokenizer is implemented by external plugins loaded dynamically via *.so files. It follows the implementation semantics of the Tokenizer interface.

Think carefully before modifying this interface, as it would break users' plugins.

type Tokenizer 

type Tokenizer interface {

	// Name is name of tokenizer. This should be unique.
	Name() string

	// Type returns the string representation of the typeID that we care about.
	Type() string

	// Tokens return tokens for a given value. The tokens shouldn't be encoded
	// with the byte identifier.
	Tokens(value interface{}) ([]string, error)

	// Identifier returns the prefix byte for this token type. This should be
	// unique. The range 0x80 to 0xff (inclusive) is reserved for user-provided
	// custom tokenizers.
	Identifier() byte

	// IsSortable returns true if the tokenizer can be used for sorting/ordering.
	IsSortable() bool

	// IsLossy() returns true if we don't store the values directly as index keys
	// during tokenization. If a predicate is tokenized using an IsLossy() tokenizer,
	// then we need to fetch the actual value and compare.
	IsLossy() bool
}

Tokenizer defines what a tokenizer must provide.
