描述

I have an array field with the entries [foo, foobar, bar] and search for foo. The highlighting then returns for that field

[<em>foo</em>, <em>foo</em>bar]

I would like it to return

[<em>foo</em>, <em>foo</em>bar, bar]

I did try to set no_match_size as described on http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-request-highlighting.html but that didn't work. Is there any way to make elasticsearch behave the way I want?

研究方向
Review the issue comments for previous discussions and attempts. Examine the highlighting code in Elasticsearch's search module, particularly the handling of array fields and no match size. Understand how the current implementation returns only matching entries and design a change to include non matching entries.
