That behavior is correct basically. The keywords field is of type
"text", text is a field type that uses stemming, thus the "jumbled" results.

For facets I recommend to use field types that do not do stemming, like
string. Since you don't want to modify the schema you just use a dynamic
field:

keywords_stringM = SOLR_MULTIVALUE
keywords_stringM {
  field = keywords
}

Now just use that keywords_stringM field to create the facet.

So "keywords" is a name you can choose on your own, then it is followed
by an underscore (_) to separate the name from the type, "string" is the
type and lastly "M" marks a multivalue field, whereas "S" would be
single value.

You can have a look at the end in
EXT:solr/resources/solr/typo3cores/conf/general_schema_fields.xml for
all the dynamic field types that are available.
