搜索 debug - 判断文档是由哪个查询语句召回的
如何判断用户输入的查询词，是哪部分命中了 ES 索引中的字段？比如用户输入“葡萄苹果”进行搜索，在查询分析过程会对“葡萄苹果”进行分词，并且进行同义词扩展，最终会以用户输入的查询词和扩展出来的同义词，进行分词之后，再查询 ES spuindex 索引的 spu_name_mt 字段，输入如下查询语句，可以追踪究竟是哪些 term 召回了这些文档。
{
"query":{
"bool" : {
"must" : [
{
"bool" : {
"should" : [
{
"constant_score" : {
"filter" : {
"bool" : {
"must" : [
{
"term" : {
"spu_name_mt" : {
"value" : "苹果",
"boost" : 1.0,
"_name":"spu_name_mt_苹果"
}
}
}
],
"adjust_pure_negative" : true,
"boost" : 1.0
}
},
"boost" : 4.0
}
},
{
"constant_score" : {
"filter" : {
"bool" : {
"must" : [
{
"term" : {
"spu_name_mt" : {
"value" : "平安",
"boost" : 1.0,
"_name":"spu_name_mt_平安果-平安"
}
}
},
{
"term" : {
"spu_name_mt" : {
"value" : "果",
"boost" : 1.0,
"_name":"spu_name_mt_平安果-果"
}
}
}
],
"adjust_pure_negative" : true,

}
}
返回的结果如下，从 matched_queries 字段可以看出是哪些词召回了此文档。非常有利于 debug。
