Solr 如何将搜索范围缩小到特定品牌，并在单个查询中获得该品牌的所有兄弟姐妹？

Question

当我输入这个url

http://localhost:8983/solr/shop/select?facet.field=brand&facet=on&facet.mincount=1&fl=name,brand,cat&q=mobile

我得到了关注

response {
  "responseHeader":{
    "status":0,
    "QTime":0,
    "params":{
      "q":"mobile",
      "facet.field":"brand",
      "fl":"name,brand,cat",
      "facet.mincount":"1",
      "facet":"on"}},
  "response":{"numFound":7,"start":0,"docs":[
      {
        "name":"moto g",
        "brand":"motorola",
        "cat":["mobile"]},
      {
        "name":"moto x",
        "brand":"motorola",
        "cat":["mobile"]},
      {
        "name":"iphone 5",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 4",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 5c",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 4s",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 5s",
        "brand":"apple",
        "cat":["mobile"]}]
  },
  "facet_counts":{
    "facet_queries":{},
    "facet_fields":{
      "brand":[
        "apple",5,
        "motorola",2]},
    "facet_ranges":{},
    "facet_intervals":{},
    "facet_heatmaps":{}}}

现在我想将搜索范围缩小到 apple 品牌的手机。为此，我使用这样的过滤器查询：

http://localhost:8983/solr/shop/select?facet.field=brand&facet=on&facet.mincount=1&fl=name,brand,cat&q=mobile&fq=brand:apple

我得到了这个结果：

{
  "responseHeader":{
    "status":0,
    "QTime":1,
    "params":{
      "q":"mobile",
      "facet.field":"brand",
      "fl":"name,brand,cat",
      "facet.mincount":"1",
      "fq":"brand:apple",
      "facet":"on"}},
  "response":{"numFound":5,"start":0,"docs":[
      {
        "name":"iphone 5",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 4",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 5c",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 4s",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 5s",
        "brand":"apple",
        "cat":["mobile"]}]
  },
  "facet_counts":{
    "facet_queries":{},
    "facet_fields":{
      "brand":[
        "apple",5]},
    "facet_ranges":{},
    "facet_intervals":{},
    "facet_heatmaps":{}}}

我对结果很满意。但我也希望 facet_fields 包含 apple 和 motorola。简而言之，我需要以下结果：

{
  "responseHeader":{
    "status":0,
    "QTime":1,
    "params":{
      "q":"mobile",
      "facet.field":"brand",
      "fl":"name,brand,cat",
      "facet.mincount":"1",
      "fq":"brand:apple",
      "facet":"on"}},
  "response":{"numFound":5,"start":0,"docs":[
      {
        "name":"iphone 5",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 4",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 5c",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 4s",
        "brand":"apple",
        "cat":["mobile"]},
      {
        "name":"iphone 5s",
        "brand":"apple",
        "cat":["mobile"]}]
  },
  "facet_counts":{
    "facet_queries":{},
    "facet_fields":{
      "brand":[
        "apple",5,
        "motorola",2]},
    "facet_ranges":{},
    "facet_intervals":{},
    "facet_heatmaps":{}}}

提前感谢您的回答。

您可以使用 filter tagging and filter exclusion 始终获得完整的方面列表，而不管特定的过滤器。

q=mobile&fq={!tag=brand}brand:apple&facet=on&facet.field={!ex=brand}brand
