Description

Consider a configset with a  solrconfig.xml that includes a snippet like this...

<str name="param.check">${custom.prop:customDefVal}</str>

...this custom.prop can be set when doing a CREATE command for a collection that uses this configset, using the property.* prefix as noted in the reg-guide...

property.name=value

Optional

Default: none

Set core property name to value. See the section Core Discovery for details on supported properties and values.

...BUT....

These values can not be changed by using the MODIFYCOLLECTION command, in spite of the ref-guide indicating that it can be used to modify custom property.* attributes...

The attributes that can be modified are:

• replicationFactor

• collection.configName

• readOnly

• other custom properties that use a property. prefix
  See the CREATE action section above for details on these attributes.
