tokenStream
TokenStream tokenStream(Analyzer analyzer, TokenStream reuse)
Creates the TokenStream used for indexing this field. If appropriate, implementations should use the given Analyzer to create the TokenStreams.- Parameters:
analyzer
- Analyzer that should be used to create the TokenStreams fromreuse
- TokenStream for a previous instance of this field name. This allows custom field types (like StringField and NumericField) that do not use the analyzer to still have good performance. Note: the passed-in type may be inappropriate, for example if you mix up different types of Fields for the same field name. So it's the responsibility of the implementation to check.- Returns:
- TokenStream value for indexing the document. Should always return a non-null value if the field is to be indexed
