symfony - elasticsearch不会返回所有匹配

Question

我正在使用Symfony 2.3和ElasticSearchBundle 3.0。我在搜索中实现了两个字段。搜索可正常运行，但不会显示所有结果。例如:当我搜索a关键字时，命中数为33次命中，但仅返回10个结果。

如何显示所有匹配？

Answer 1

默认情况下，Elasticsearch仅返回前10个结果。可以通过指定from and size parameters来修改此设置。请注意，将所有结果显示在一页上很少有意义，而是使用具有可控制数量的已查看项目的分页。

如果您希望所有点击都在一页上，也请考虑使用scroll api，因为在获得大量结果时，深度分页可能会非常低效。
