Hi Shawn, thanks for the quick reply.
I've looked at both methods and I think that they won't work for a number of
reasons:
1)
uniqueKey:
I could use the uniqueKey and overwrite the original document but I need to
remove the documents which
are not on my new input list and the issue with the uniqueKey method is I don't
know what to delete.
Documents on the index:
"docs": [
{
"id":"1"
"keyField":"A"
},{
"id":"2"
"keyField":"A"
},{
"id":"3"
"keyField":"B"
}
]
New Documents to go on index
"docs": [
{
"id":"1"
"keyField":"A"
},{
"id":"3"
"keyField":"B"
}
]
I would never know that id:2 should be deleted. (on some new document lists the
delete list could be in the millions).
2)
openSearcher:
My openSearcher is set to false and I've also commented out autoSoftCommit so I
don't get a partial list being returned on a query.
<!--
<autoSoftCommit>
<maxTime>${solr.autoSoftCommit.maxTime:1000}</maxTime>
</autoSoftCommit>
-->
So is there another way to keep the original set of documents until the new set
has been added to the index?
Thanks
Russ.

As long as you don't have any commits with openSearcher=true happening between
the delete and the insert, that would work ... but why go through the manual
delete if you don't have to?
If you define a suitable uniqueKey field in your schema, simply indexing a new
document with the same value in the uniqueKeyfield as an existing document will
delete the old document.
