我使用 es6.5 做查询,涉及到高亮查询,
(1).当使用match时,高亮能正常使用;
(2).使用terms查询时
1.若词较少,高亮也正常;
2.词过多,超过了17个,则高亮就无效
这是我的mapping

Highlighters don’t reflect the boolean logic of a query when extracting terms to highlight. Thus, for some complex boolean queries (e.g nested boolean queries, queries using minimum_should_match etc.), parts of documents may be highlighted that don’t correspond to query matches.
