我是弹性搜索的新手,我正在使用亚马逊的弹性搜索 5.3。这是我的 json 数据
[
{
"Sl. No.": 5,
"Code No.": "0101.21.00",
"Name of Commodity": "Live Horses"
},
{
"Sl. No.": 6,
"Code No.": "0101.29.00",
"Name of Commodity": "some name"
}
]
这是我在 nodejs 中用于数据加载的设置。
var client = new elasticsearch.Client({
host: 'https://search-testdomain-mydomain.amazonaws.com',
log: 'trace'
});
for (var i = 0; i < jsonfile.length; i++ ) {
client.create({
index: esindex, // name your index
type: estype, // describe the data thats getting created
id: i, // increment ID every iteration
body: jsonfile[i]
}, function(error, response) {
if (error) {
console.error(error);
return;
}
});
}
搜索代码是
client.search({
index: esindex,
type: estype,
body: {
query: {
"multi_match" : {
"query": searchQuery,
"fields": [ "Sl. No.", "Name of Commodity", "Code No."],
"operator": "or" ,
"analyzer":"standard"
}
}
}
}).then(function (resp) {
console.log(resp);
});
当我搜索字符串时,它给出了正确的结果。IE
curl -XGET https://search-testdomain-mydomain.amazonaws.com/product/products/_search?pretty -d'
{
"query": {
"multi_match": {
"query": "Live Horses",
"fields": [
"Sl. No.",
"Name of Commodity",
"Code No."
],
"operator": "or"
}
}
}'
但是当我为整数做时,它没有结果
curl -XGET https://search-testdomain-mydomain.amazonaws.com/product/products/_search?pretty -d'
{
"query": {
"multi_match": {
"query": 1,
"fields": [
"Sl. No.",
"Name of Commodity",
"Code No."
],
"operator": "or"
}
}
}'
它适用于正常的 curl 调用,无需指定任何文件
curl -XGET https://search-testdomain-mydomain.amazonaws.com/product/products/_search?pretty -d'
{
"query": {
"query_string": {
"query": 1
}
}
}'
我读了很多帖子说我们需要添加分析器,即标准来处理整数。我尝试在创建时添加,但它抛出了错误。我需要添加边缘 NGram分析器吗?我没有得到如何处理这个。如何在nodejs中添加分析器..请有人帮我解决这个问题?
