Re: How to define a multivalued string type "langid.langsField" in solrconfig.xml

[Jan Høydahl <ja...@cominvent.com>]

Hi,

The documentation for this features says:
> langid.langsField
> 
> Specifies the field to output a list of detected languages into. This must be a multiValued String field. If you use langid.map.individual, each detected language will be added to this field.

Your langid.langsField field must be defined in the schema as multiValued, not in the requesthandler config.
As far as I remember, the langid.map.individual will only take effect if you have langid.map=true, i.e. you cannot detech langs from individual fields and have them be added to the langsField without also doing mapping.
