我有一个脚本，它基于url索引http://example.com/sitemap.index.xml生成站点地图，其中index是一个数字>0，定义了每个区块中应该包括哪些结果。
$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，每次我访问http://example.com/sitemap.1.xml或http://example.com/sitemap.2.xml时，从ES返回的结果都完全相同。它返回50结果（每个碎片10个），但似乎不计算from = 0、from = 10000。
我正在使用elasticsearch-php作为ES库。
有什么想法吗？
在Java中，可以按照
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;
}
}
希望能有所帮助。
