Shinya Kasatani updated LUCENE-2910:
------------------------------------
Description:
When you use the Highlighter combined with N-Gram tokenizers such as
CJKTokenizer and try to highlight the phrase that appears around 50th term in
the field, the highlighted phrase is shorter than expected.
{noformat}
e.g. Highlighting "fooo" in the following text with bigram tokenizer:
"0---------1---------2---------3---------4---------fooo---"
Expected: "0---------1---------2---------3---------4---------<B>fooo</B>---"
Actual: "0---------1---------2---------3---------4---------f<B>ooo</B>---"
{noformat}
