Hi Mark:
Thanks, a few things were resolved.
1. I was running into heap memory issues on the new node, and the Cluster
state went form being Yellow to Green almost immediately.
2. The problem with my query was not so much with lack of data or data not
being replicated/copied over to the new node, But something see hokey with
the date math.
The query I was using before :
{
"query": {
"bool": {
"must": [
{"range": {
"DOC_DATE": {
"from": "now-36d",
"to": "now-35d"
}
}}
]
}
}
}
this would result in a number of documents.
However after I added the new node: the same query would not return any
docs. But when I changed
it to
{
"query": {
"bool": {
"must": [
{"range": {
"DOC_DATE": {
"from": "2014-11-14T00:00:00Z",
"to": "2014-11-15T00:00:00Z"
}
}}
]
}
}
}
I got documents.
Now the question is whats the problem with my prior query (if any).
Thanks
Ramdev
