A search with an empty fields param causes a NullPointerException or a runaway process

An empty fields[] array either returns a NullPointerException, or causes a runaway process. Try this:

curl -XGET 'http://192.168.5.100:9200/_all/_search'  -d '
{
   "fields" : [],
   "query" : {
      "matchAll" : {}
   }
}
'

thanks

A search with an empty fields param causes a NullPointerException or a runaway process. Changed logic for an empty fields array, where it won't return the source in this case. Closed by 4b04db9.
