Solr 7.5 multi-valued fields will not update with multiple values

[Eivind Hodneland]

Hi,

I am running a Solr 7.5 index for a customer.
I have recently discovered that none of the multivalued string/text fields are 
filled with more than one value each.

Example of indexing (edited and abbreviated):
curl -X POST -H 'Content-Type: application/json' 
'http://localhost:18080/solr/customer_core/update/' --data-binary 
'[{"id":"MyId","author_fullname":["Author 1","Author 2","Author 3"]}]'

The multivalued field author_fullname only gets one value, namely "Author 1".
This is also the case for the other multivalued fields in the schema.

Definition of author_fullname and its corresponding type from managed-schema:

Java - setting multi-valued fields

[Eivind Hodneland]

Hi,

My customer has a Solr index with a large amount of fields, many of these are 
multivalued (type="string", multiValued="true").

I am having problems with setting the values for these fields in my Java update 
processors.
Example:
String[] values = new String[] {"value 1", "value 2" };
inputDoc.setField (multiFieldName, values);

However, only "value 1" is present in the index after updating.
What is the best / correct way to make this work?

Hi,

Thanks for your input.
However, this approach did not work either, it gave the same result as 
previously.

Is there perhaps a different approach that could be used, other methods etc. ?

HI

Example:

String[] values = new String[] {“value 1”, “value 2” };

inputDoc.setField (multiFieldName, values);


Can you try once to change the array to list ?

List values = new ArrayList<>();

values.add("value 1");

values.add("value 2");

inputDoc.setField (multiFieldName, values);



regards
