我有一个脚本可以根据网址索引http://example.com/sitemap.index.xml
生成站点地图,其中index
是一个数字>0
,用于定义每个块中应包含的结果。
$chunk = 10000;
$counter = 0;
$scroll = $es->search(array(
"index" => "index",
"type" => "type",
"scroll" => "1m",
"search_type" => "scan",
"size" => 10,
"from" => $chunk * ($index - 1)
));
$sid = $scroll['_scroll_id'];
while($counter < $chunk){
$docs = $es->scroll(array(
"scroll_id" => $sid,
"scroll" => "1m"
));
$sid = $docs['_scroll_id'];
$counter += count($docs['hits']['hits']);
}
// ...
现在每次访问http://example.com/sitemap.1.xml
或http://example.com/sitemap.2.xml
时,ES返回的结果都完全相同。它返回50
个结果(每个分片10个),但似乎不计算from = 0
,from = 10000
。
我使用elasticsearch-php
作为ES库。
有什么想法吗?

在Java中,可以按照以下方式完成
QueryBuilder query = QueryBuilders.matchAllQuery();
SearchResponse scrollResp = Constants.client.prepareSearch(index)
.setTypes(type).setSearchType(SearchType.SCAN)
.setScroll(new TimeValue(600000)).setQuery(query)
.setSize(500).execute().actionGet();
while (true) {
scrollResp = Constants.client
.prepareSearchScroll(scrollResp.getScrollId())
.setScroll(new TimeValue(600000)).execute().actionGet();
System.out.println("Record count :"
+ scrollResp.getHits().getHits().length);
total = total + scrollResp.getHits().getHits().length;
System.out.println("Total record count: " + total);
for (SearchHit hit : scrollResp.getHits()) {
//handle the hit
}
// Break condition: No hits are returned
if (scrollResp.getHits().getHits().length == 0) {
System.out.println("All records are fetched");
break;
}
}
希望它有所帮助。
