この JSON でインデックスとマッピングを作成しました
// 1st Mapping
http://localhost:9200/hdm/entities/_mapping
{
"entities" : {
"properties": {
"name": { "type": "string", "boost": 2.0, "analyzer": "snowball" },
"description": { "type": "string", "analyzer": "nGram" }
}
}
}
// 2nd Mapping
http://localhost:9200/hdm/products/_mapping
{
"products": {
"_parent": { "type": "entities" },
"properties": {
"name": { "type": "string", "boost": 2.0, "analyzer": "snowball" },
"code": { "type": "string", "analyzer": "snowball" },
"segment": { "type": "string", "analyzer": "snowball" },
"description": { "type": "string", "analyzer": "snowball" }
}
}
}
JSONを使用して、このインデックスのいくつかのドキュメントにインデックスを付けました
http://localhost:9200/hdm/entities/100
{
"name":"Entity 001",
"description":"this is the company or an organization which provides the whole medicine, tablets injunction for the problem of human being those noting worth gaining was ever gained without effort
",
"itype":"entities"
}
http://localhost:9200/hdm/products/101?parent=100
{
"name":"biorich",
"description":"the tablet para is used to rectify the person from the all types of pain in the body, kingston , car, bat, ball, description of the products",
"code":"COD19202",
"segment":"SEG1022",
"itype":"products"
}
検索には、この JSON を使用しました
{
"query": {
"filtered": {
"query": {
"bool": {
"should": [
{
"has_child": {
"type": "products",
"query": {
"query_string": {
"query": "tab"
}
}
}
},
{
"query_string": {
"query": "tablet"
}
}
]
}
},
"filter": {
"or": [
{
"term": {
"itype": "entities"
}
}
]
}
}
}
}
結果は得られませんでしたが、クエリ文字列をこのように変更すると、結果が得られました
"query_string": {
"default_field" : "description"
"query": "tablet"
}
nGram アナライザーの結果を取得するには、クエリ文字列で default_field について言及する必要がありますか? 私のアナライザー構成は次のとおりです
index.analysis.analyzer.mynGram.type: custom
index.analysis.analyzer.mynGram.tokenizer: standard
index.analysis.analyzer.mynGram.filter: [lowercase, mynGramFilter]
index.analysis.filter.mynGramFilter.type: nGram
index.analysis.filter.mynGramFilter.min_gram: 1
index.analysis.filter.mynGramFilter.max_gram: 10
