有几种方法可以解决这个问题：
无限加载渲染所有结果
onAllData将给出sizeprop 中指定的结果数。通常，设置一个非常高的值并不是一个好主意，size因为它会花费更多时间来获取和呈现结果。一个很好的替代方法是通过将paginationprop 设置为false并在 prop 中设置一个值来使用无限滚动，该值size告诉组件在到达列表末尾时要获取多少结果。
使用滚动 API 获取所有结果
tl;博士演示
笔记
这个答案使用了 web 的响应式搜索（用于演示），但您可以在响应式搜索原生中使用相同的道具，因为 API 是相同的。
如果您只对渲染结果感兴趣，上述方法可以正常工作。但是，如果您希望获取当前查询的所有结果，您可以使用 Elasticsearch 的滚动API。您可以使用ReactiveList获取当前查询，然后将其与滚动 API 一起使用。
为此，您可以使用以下onQueryChange道具ReactiveList：
首先指定一个onQueryChangeprop，ReactiveList它接收上一个和当前的查询作为参数：
onQueryChange={(prev, next) => ...}
每次更改查询时都会调用此函数，因此您可以编写逻辑以在需要时获取当前查询（在next参数中接收）的命中。
滚动 API 调用以以下格式返回结果：

接收到的值_scroll_id可以传递给滚动 API 以获取下一组结果，依此类推，直到点击次数为零。
笔记
如果您的集群有大量数据，那么每次查询更改时运行此逻辑来获取所有结果并不是一个好主意。您可以添加一个条件来限制获取的结果数量或将当前查询存储在状态中，并仅在需要时获取所有结果。
这是一个示例，说明如何使用ReactiveList. 在示例中，每次查询更改时我都会获取结果，但您可以修改它以有条件地获取结果：
在您的render功能中：
<ReactiveList
...
size={10}
onQueryChange={this.handleQueryChange}
/>
这是handleQueryChange函数的外观。这将为您提供当前查询的所有结果：
handleQueryChange = async (prev, next) => {
// avoid fetching the results for match_all query since dataset is large
if (next && !next.query.match_all) {
console.log('Fetching all results for query:', next);
// modify the query size here if needed (currently it is 10)
// initial url to obtain scroll id is different
const initialResults = await this.fetchResults(next, url);
// keep scrolling till hits are present
// NOTE: careful if you've a lot of results,
// in that case you might want to add a condition to limit calls to scroll API
const scrollResults = await this.fetchScrollResults({
scroll: "1m",
scroll_id: initialResults._scroll_id
});
// combine the two to get all results
// concat hits from initialResults with hits from scrollResults
const allResults = initialResults.hits.hits.concat(scrollResults);
console.log(`${allResults.length} results found:`, allResults);
}
};
它最初使用两个函数来获取结果，然后使用scroll_id. 两者的端点不同，您可以在demo中找到。这是第一个的fetchResults样子：
fetchResults = (query, api) => {
return fetch(api, {
method: "POST",
headers: {
"content-type": "application/json",
Authorization: `Basic ${btoa(credentials)}`
},
body: JSON.stringify(query)
})
.then(res => res.json())
.catch(err => console.error(err));
};
将fetchScrollResults使用滚动 API 获取结果，直到获得的命中为 0。
fetchScrollResults = async query => {
const res = await this.fetchResults(query, scrollUrl);
const { hits } = res.hits;
if (hits.length) {
return [
...hits,
...(await this.fetchScrollResults({
scroll: "1m",
scroll_id: res._scroll_id
}))
];
}
return [];
};
检查演示，结果将出现在控制台中。
