根据SOLR中的特定字段进行计数

Question

How to return the count of a field with each object in Solr

When I do fq=verify_ix:1 I have a response below, I want to get count where verify_ix = 1 in the response too. How can I do that?

"response": {
    "numFound": 9484,
    "start": 0,
    "maxScore": 1,
    "docs": [
      {
        "id": "10000000000965509",
        "description_s": "No Description",
        "recommendation_ix": 0,
        "sId_lx": 30005938,
        "sType_sx": "P",
        "condition_ix": 1000,
        "verify_ix": 1
      },
      .
      .
      .
      {
        "id": "10000000000965734",
        "description_s": "No Description",
        "recommendation_ix": 1,
        "sId_lx": 30005947,
        "sType_sx": "P",
        "condition_ix": 2000,
        "verify_ix": 1
      }

If you want counts of the different values for a given field, you can send a request to Solr with facet=true and facet.field=verify_ix . For counts over all records, set q=*:* . If you don't want to see any rows returned, you can set rows=0 .

See here for more details on faceting:

(I tested this with Solr 5, but faceting should work with Solr 4 as well.)
