Question

我正在使用Symfony 2.3和ElasticSearchBundle 3.0。我为搜索实现了两个字段。搜索工作正常，但不显示所有结果。例如：当我搜索a关键字时，点击次数为33次点击，但只返回10次结果 config.php

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，在一个页面上显示所有结果很少有意义，而是使用可控量的可查看项目进行分页。

如果您希望一个页面上的所有匹配也考虑使用scroll api，因为在获得大量结果时，深度分页会变得非常低效。

elasticsearch不会返回所有匹配
