How to delete SOLR indexed data by query with curl?

Question

I have a SOLR schema.xml like this:

Answer 1

In this way would be easier: curl "http://46.231.77.98:7979/solr/collection/update/?commit=true&stream.body=<delete><query>(cartype:stationwagon)AND(color:blue)</query></delete>"

It's a simple GET request and you have just to add the parameter
stream.body=<delete><query>(cartype:stationwagon)AND(color:blue)</query></delete> to the query string.

Answer 2

You have to add query tag.

<delete><query>(cartype:stationwagon)AND(color:blue)</query></delete>

Answer 3

Using JSON instead of XML:

curl -g "http://localhost:8983/solr/$core/update" \
     -H 'Content-Type: application/json' \
     -d '{"delete":{"query":"field:value"}}'
