HeXin created SOLR-5193:
---------------------------
Summary: Atomic update should add function to check the whether
uniqueKey is already existing
Key: SOLR-5193
URL: https://issues.apache.org/jira/browse/SOLR-5193
Project: Solr
Issue Type: Improvement
Components: update
Affects Versions: 4.4
Reporter: HeXin
When we use below code to update doc:
curl http://localhost:8983/solr/update -H 'Content-type:application/json' -d '
[
{
"id" : "TestDoc1",
"publisher" : {"set":"TestPublisher"}
}
]'
Sometimes we want that the publisher field updates only when the id of TestDoc1
has already existed in solr. Because if the "TestDoc1" doesn't exist in solr
before, it is useless to add just one field for the doc.
Therefore, i think we can support additional syntax tocheck whether the
uniquekey is already existing just like below:
curl http://localhost:8983/solr/update -H 'Content-type:application/json' -d '
[
{
"id" : {"check": "TestDoc1"}
"publisher" : {"set":"TestPublisher"}
}
]'
