Subject: [PATCH] use inline expression script for preferring short module
 names

The 'expression' language is faster, more secure, and supported on
modern versions of Elasticsearch. It requires numeric fields. Now that
we have the numeric `documentation_length` field, we can use it to
prefer shorter names rather than needing to put files onto the ES
servers.
