Question

在索尔,我怎样才能在一面数上排成一面呢?我知道我有可以跳过记录的一个面数,但是我怎么知道有多少个面数记录呢?

Answer 1

You need to apply Solr Patch SOLR-2242 to get the Facet distinct count.
The total count can be helpful to paginate.

Answer 2

在Solr 5.3及以上,使用面图获得文件总数,

那对于你们是纯洁的、

facet=on

例如,例如

http://<solr-url>/select?facet=on&indent=on&q=*:*&rows=0&wt=json

然后得到一个侧面对象的响应, 它会看起来像,

{
  "responseHeader":{
    "zkConnected":true,
    "status":0,
    "QTime":3,
    "params":{
      "q":"*:*",
      "indent":"on",
      "rows":"0",
      "facet":"on",
      "wt":"json"}},
  "response":{"numFound":8,"start":0,"maxScore":1.0,"docs":[]
  },
  "facet_counts":{
    "facet_queries":{},
    "facet_fields":{},
    "facet_ranges":{},
    "facet_intervals":{},
    "facet_heatmaps":{}}
}

您从 reponse 获得 numFound ,这是该索尔核心中的记录的总数。

<更强 > 另一种方式

如果有任何面对面的查询,请使用,

facet=on&json.facet={}

例如,例如

http://<solr-url>/select?facet=on&indent=on&json.facet={}&q=*:*&rows=0&wt=json

然后得到一个侧面对象的响应, 它会看起来像,

{
  "responseHeader":{
    "zkConnected":true,
    "status":0,
    "QTime":3,
    "params":{
      "json.facet":"{}",
      "q":"*:*",
      "indent":"on",
      "rows":"0",
      "facet":"on",
      "wt":"json"}},
  "response":{"numFound":80,"start":0,"maxScore":1.0,"docs":[]
  },
  "facet_counts":{
    "facet_queries":{},
    "facet_fields":{},
    "facet_ranges":{},
    "facet_intervals":{},
    "facet_heatmaps":{}},
  "facets":{
    "count":80}}

从 facets 对象获得 count count ,这是记录的最大数量。
