如何使用Solr Search获取唯一的disintct值

Question

i'm new to solr search.I want to get disinct values of fields using solr. I'm using &rows=0&facet=on&facet.field=fieldname&wt=json

Output:

facet_fields":{"packagename":["bangalore",2,"hyerabadd",2,"australia",3]

This is my code for decode above output:

<?php
header("Content-type:text/json");

$data=file_get_contents("http://localhost:8984/solr/collection1/select?q=*:*&rows=0&facet=on&facet.field=fieldname&wt=json");

$res=json_decode($data);

foreach($res->facet_counts->facet_fields as $doc){
    foreach($doc as $value){
      echo $value; 
    }
}
?>

Output after decode:

bangalore
2
hyderabad
2
australia
3

but,here i dont't want to display those numbers(min count).

Look here

You can specify how the result should be returned in the JSON. Default is how it is shown above in your question. With json.nl=arrarr added to your query it will look like this

facet_fields":{ "packagename":[["bangalore",2],["hyerabadd",2],["australia",3]]

and it should be easier to distinguish between name and count
