How can I access filename using elasticsearch from a code like this?
{
"_index" : "fscrawler-rest-tests_doc",
"_type" : "_doc",
"_id" : "dd18bf3a8ea2a3e53e2661c7fb53534",
"_version" : 1,
"found" : true,
"_source" : {
"content" : "This file contains some words.\n",
"meta" : {
"raw" : {
"X-Parsed-By" : "org.apache.tika.parser.DefaultParser",
"Content-Encoding" : "ISO-8859-1",
"Content-Type" : "text/plain; charset=ISO-8859-1"
}
},
"file" : {
"extension" : "txt",
"content_type" : "text/plain; charset=ISO-8859-1",
"indexing_date" : "2017-01-04T21:01:08.043",
"filename" : "test.txt"
},
"path" : {
"virtual" : "test.txt",
"real" : "test.txt"
}
}
}
