IndexableFieldtokenStream in interface IndexableFieldanalyzer - 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.Copyright © 2000-2017 Apache Software Foundation. All Rights Reserved.
