Summary: Add a custom separator break iterator
Key: LUCENE-6485
URL: https://issues.apache.org/jira/browse/LUCENE-6485
Project: Lucene - Core
Issue Type: Improvement
Reporter: Luca Cavanna
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.
