Why is Solr throwing exceptions on unfound text files after insttalling Apache Solr Multilingual config files?
Is the configuration of such files not the purpose of the Apache Solr Multilingual module ?


Seems the answer is 'no'.  I manually created 6 text files per language in my solr config and solr started without complaint. 

Each language needs each of these text files:

compoundwords_&lt;lang&gt;.txt
mapping-FoldToASCII_&lt;lang&gt;.txt
mapping-ISOLatin1Accent_&lt;lang&gt;.txt
protwords_&lt;lang&gt;.txt
stopwords_&lt;lang&gt;.txt
synonyms_&lt;lang&gt;.txt


where 'lang' is the Drupal language code which can be confirmed by looking over the schema.xml kicked out by Solr Multilingual Module . for example: 'en', 'es', 'de' ...

I copied the contents of each of said files from the Solr Multilingual Module config. forms
