I am hitting same issue with 2 shards
curl "localhost:9200/codeindexroute/_settings?pretty"
{
"codeindexroute" : {
"settings" : {
"index" : {
"index" : {
"refresh_interval" : "-1"
},
"refresh_interval" : "1000",
"number_of_shards" : "2",
"number_of_replicas" : "0",
"version" : {
"created" : "1020099"
},
"uuid" : "p_8eAj0GSA-XNUWtQD6fLg"
}
}
}
}
Now I index the document
curl "localhost:9200/codeindexroute/filecontracts/?routing=abc" -d
@data-file.json
{"_index":"codeindexroute","_type":"filecontracts","_id":"n8-pLUU4TnS6LvhCDFIXkQ
","_version":1,"created":true}
curl "localhost:9200/codeindexroute/filecontracts/_search?routing=bbb"
{"took":1,"timed_out":false,"_shards":{"total":1,"successful":1,"failed":0},"hit
s":{"total":1,"max_score":1.0,"hits":[{"_index":"codeindexroute","_type":"fileco
ntracts","_id":"n8-pLUU4TnS6LvhCDFIXkQ","_score":1.0,"_source":{
"content
":"I am Happy", "contentid": "abcdedf", "filepath" : "\\test1\test1.txt",
"parsertype" : "txt"}}]}}
IMHO If hash collision is an issue then routing cannot be used at all and
it is not useful.It has to be definite
