Problem with indexing empty lists / tuple (`None`) in Solr string fields #366

Closed laulaz closed 1 month ago

laulaz commented 8 months ago

Empty Dexterity fields of type List / Tuple (= None) are indexed by collective.solr in the <add> like this :

<field name="my_field" update="set">None</field>

As it is defined in Solr schema as string fields, we end up with : 

<arr name="my_field">
      <str>None</str>
</arr>

After catalog.searchResults, the returned indexed value is ["None"]. We should have no arr instead.

It works correctly for List / Tuple fields (like Plone Subjects) only when there is a missing_value=() or missing_value=[].
