我们在弹性搜索 (ES) 上使用两种类型的文档:项目和插槽,其中项目是插槽文档的父级。我们使用以下命令定义索引:
curl -XPOST 'localhost:9200/items' -d @itemsdef.json
其中itemsdef.json
有以下定义
{
"mappings" : {
"item" : {
"properties" : {
"id" : {"type" : "long" },
"name" : {
"type" : "string",
"_analyzer" : "textIndexAnalyzer"
},
"location" : {"type" : "geo_point" },
}
}
},
"settings" : {
"analysis" : {
"analyzer" : {
"activityIndexAnalyzer" : {
"alias" : ["activityQueryAnalyzer"],
"type" : "custom",
"tokenizer" : "whitespace",
"filter" : ["trim", "lowercase", "asciifolding", "spanish_stop", "spanish_synonym"]
},
"textIndexAnalyzer" : {
"type" : "custom",
"tokenizer" : "whitespace",
"filter" : ["word_delimiter_impl", "trim", "lowercase", "asciifolding", "spanish_stop", "spanish_synonym"]
},
"textQueryAnalyzer" : {
"type" : "custom",
"tokenizer" : "whitespace",
"filter" : ["trim", "lowercase", "asciifolding", "spanish_stop"]
}
},
"filter" : {
"spanish_stop" : {
"type" : "stop",
"ignore_case" : true,
"enable_position_increments" : true,
"stopwords_path" : "analysis/spanish-stopwords.txt"
},
"spanish_synonym" : {
"type" : "synonym",
"synonyms_path" : "analysis/spanish-synonyms.txt"
},
"word_delimiter_impl" : {
"type" : "word_delimiter",
"generate_word_parts" : true,
"generate_number_parts" : true,
"catenate_words" : true,
"catenate_numbers" : true,
"split_on_case_change" : false
}
}
}
}
}
然后我们使用以下命令添加子文档定义:
curl -XPOST 'localhost:9200/items/slot/_mapping' -d @slotsdef.json
其中slotsdef.json
有以下定义:
{
"slot" : {
"_parent" : {"type" : "item"},
"_routing" : {
"required" : true,
"path" : "parent_id"
},
"properties": {
"id" : { "type" : "long" },
"parent_id" : { "type" : "long" },
"activity" : {
"type" : "string",
"_analyzer" : "activityIndexAnalyzer"
},
"day" : { "type" : "integer" },
"start" : { "type" : "integer" },
"end" : { "type" : "integer" }
}
}
}
最后,我们使用以下命令执行批量索引:
curl -XPOST 'localhost:9200/items/_bulk' --data-binary @testbulk.json
其中 testbulk.json 包含以下数据:
{"index":{"_type": "item", "_id":35}}
{"location":[40.4,-3.6],"id":35,"name":"A Name"}
{"index":{"_type":"slot","_id":126,"_parent":35}}
{"id":126,"start":1330,"day":1,"end":1730,"activity":"An Activity","parent_id":35}
我正在尝试进行以下查询:搜索在指定日期和特定开始和结束范围内到某个位置的特定距离内有子项(插槽)的所有项目。
具有更多满足条件的插槽的项目应得分更高。
我尝试从现有样本开始,但文档非常稀缺,而且很难向前推进。
