Hi all,

We are doing a poc to use in-place updates to speed up the indexing process
at our end.
Version: v9.6.1

we are having some doubts wrt how atomic and in-place updates are being
implemented at solr

*Solr Doc Link we referred:*
https://solr.apache.org/guide/solr/latest/indexing-guide/partial-document-updates.html

As per doc,
*Atomic updates:*
This works with fields which are stored=true or docValues=true and updates
are done field wise instead of complete re-index of document

*In Place updates:*
Works with fields which are non-indexed and non-stored and updates are
field wise instead of complete re-index of document
1. This meant we cannot query on this field and cannot display the value of
the field.
May I know how this helps?

2. Found one contradictory statement in *in-place* updates section
Link
<https://solr.apache.org/guide/solr/latest/indexing-guide/partial-document-updates.html#in-place-updates>
"In regular atomic updates, the entire document is reindexed internally
during the application of the update. However, in this approach, only the
fields to be updated are affected and the rest of the documents are not
reindexed internally"

Isn't this contradictory with the atomic updates concept?

Pls let me know if we are missing some details

*Thanks & Regards,*
*Uday Kumar*
