python - TransportError 400 Elasticsearch 包含大量术语

Question

使用小术语列表进行搜索可以得到我想要的内容

In [29]: small_list
Out[29]: [8096, 8105, 8114, 8116, 8128, 8130]

In [30]: sqs.filter(id__in=small_list)
Out[30]: [<SearchResult: web.listing (pk=u'8128')>, <SearchResult: web.listing (pk=u'8130')>, <SearchResult: web.listing (pk=u'8116')>, <SearchResult: web.listing (pk=u'8105')>, <SearchResult: web.listing (pk=u'8114')>, <SearchResult: web.listing (pk=u'8096')>]

但是有数千个术语给出以下错误:

In [32]: len(big_list)
Out[32]: 6305
In [33]: sqs.filter(id__in=big_list)
Traceback (most recent call last):

默认情况下，elasticsearch 的查询条件限制为 1024 个。

以下查询适合您

sqs.filter(id__in=big_list[:1024])
