【问题描述】：
我的搜索结果只有 1 个字词出现在与查询中的两个字词匹配的结果上方。以下是我的设置
搜索查询
POST index1/_search
{
"size": 5,
"query": {
"bool": {
"should": [
{
"match": {
"content": {
"query": "devtools tutorial"
}
}
}
]
}
}
}
使用的设置和映射：
{
"mappings": {
"properties": {
"content": {
"type": "text"
},
"title": {
"type": "text"
}
}
}
}
我一直用于测试目的的示例文档。我希望带有 _id : 3 的文档出现在带有 _id:4 的文档上方，因为它同时具有查询中的两个术语：
