The term we are searching for (just a numeric ID) exists in two places
depending on the document. Either as an "entry_human_id" which is the ID of
that specific document, or within an array of "linked_entry_human_ids" where
the document is linked to another document.
What we want is the document that matches the ID to the entry_human_id comes
above any documents that match the ID in the linked_entry_human_ids (hence the
boost on entry_human_id), but this doesn't seem to be happening.
Would that be better suited to a query-time boost? If so, is there a specific
way to boost a term in the query as I cannot see one in the readme.
