如果没有在索引的mappings属性中定义运行时字段,那么也可以通过_search查询时,通过runtime_mappings来定义运行时字段。 GET my-index-000001/_search { "runtime_mappings": { "day_of_week": { "type": "keyword", "script": { "source": "emit(doc['@timestamp'].value.dayOfWeekEnum....
"runtime_mappings": { "source.ip": { "type": "ip", "script": """ String sourceip=grok('%{IPORHOST:sourceip} .*').extract(doc[ "event.original" ].value)?.sourceip; if (sourceip != null) emit(sourceip); """ } }, "query": { "range": { "@timestamp": { "gte": "...
"runtime_mappings": { // 运行时映射 "weight": { // 字段 "type": "long", // 类型 "script": "emit(doc['is_publish'].value ? 1 : 0)" // 脚本 } } } 脚本字段可能会对性能产生一定的影响,具体取决于您的数据量和查询复杂性。在大规模数据集上使用脚本字段时,请确保评估和测试性能。 da...
如果我们使用之前的 runtime fields 来实现,也就是这样的: GET nyc_taxis/_search?filter_path=**.hits { "_source": false, "runtime_mappings": { "cost_per_mile": { "type": "double", "script": { "source": "emit(doc['total_amount'].value/doc['trip_distance'].value)" } } }, "...
使用脚本script: 通过script在查询时提取出运行时字段grade.corrected POST /exams/_search?size=0{"runtime_mappings": {"grade.corrected": {"type": "double","script": {"source": "emit(Math.min(100, doc['grade'].value * params.correction))","params": {"correction": 1.2}}},"aggs": {"...
采用script脚本提取运行时字段,并对运行时字段message.length进行聚合。 GET /my-index-000001/_search?size=0{"runtime_mappings": {"message.length": {"type": "long","script": "emit(doc['message.keyword'].value.length())"}},"aggs": {"message_length": {"histogram": {"interval": 10,"fie...
如果需要对布尔值进行转换,可以使用 "运行时"脚本来处理 GET myindex-2_03/_search { "fields": [ { "field": "weight" } ], "runtime_mappings": { "weight": { "type": "long", "script": "emit(doc['is_published'].value?1:0)" } } } #返回结果如下 { "took" : 1, "timed_out...
POST my-index-000001/_search{"runtime_mappings":{"category":{"type":"keyword","script":{"source":"""if (doc['navigator_ids].value.contains('123456')) {emit('123456');} else if (doc['navigator_ids].value.contains('234567')) ...
GET/test-agg-cars/_search{"runtime_mappings":{"make.length":{"type":"long","script":"emit(doc['make.keyword'].value.length())"}},"size":0,"aggs":{"make_length":{"histogram":{"interval":1,"field":"make.length"}}} 结果
