这是我们在 ES 中的映射示例:
mapping = {
'settings': {
'number_of_shards': 1,
'number_of_replicas': 0,
},
'mappings': {
'_doc': {
'properties': {
'cat': {
'type': 'keyword',
}
}
}
}
}
我们为使用 Python 测试的一些行编制了索引:
es.index('test_ind', '_doc', body={'cat': 'cat1,cat2,cat3'})
es.index('test_ind', '_doc', body={'cat': 'cat1,cat2,cat4'})
所以我尝试通过在 cat 字段上terms
运行一个操作来运行一些桶聚合:split
facet = {
"_source": ["cat"],
"aggs": {
"test": {
"terms": {
"script": {
"source": "doc['cat'].value.split(',')[0]",
}
}
}
}
}
r = es.search('test_ind', '_doc', body=facet)
但这会引发错误:
TransportError: TransportError(500, 'search_phase_execution_exception', '运行时错误')
在 ES 日志中,我可以看到以下消息:

为什么它不接受拆分操作?我们的设置有什么问题吗?
