skip update for particular field in solr

Question

I want to skip update of particular field in solr document.

I am importing data from csv to solr. added one extra field "RecCount" from managed schema as follows:

Case 1: If i set default value

<field name="RecCount" type="pint" indexed="true" stored="true" default="0"/>

when i re import data then previous value of RecCount field reset to 0 which i don't want if it is 5 then it need not to be update.

Case 2: if no default value

<field name="RecCount" type="pint" indexed="true" stored="true" />

in this case when i re-import data "RecCount" field is not getting added to document

Import shell script as follows :

wget "$1" -O $DOWNLOADFILE
$SOLR_URL -c $SOLR_CORE $DOWNLOADFILE

What is the way to skip update of RecCount field?

So what is your _actual update_ request? It seems like you're just sending the same index request to Solr, and not asking for an update. If you want to _update a document_ (and not index a new one over the old one), you [have to format your requests in a specific way](https://lucene.apache.org/solr/guide/8_5/updating-parts-of-documents.html). — MatsLindh, Jun 16 '20 at 13:14

The csv index handler allows to set a parameter called "skip" which takes the field names to skip during import.
