> Lucene currently includes a WholeBreakIterator used to highlight entire
> fields using the postings highlighter, without breaking their content into
> sentences.
> I would like to contribute a CustomSeparatorBreakIterator that breaks when a
> custom char separator is found in the text. This can be used for instance
> when wanting to highlight entire fields, value per value. One can subclass
> PostingsHighlighter and have getMultiValueSeparator return a control
> character, like U+0000 , then use the custom break iterator to break on
> U+0000 so that one snippet per value will be generated.
