[MarkLogic Dev General] lib-search, Fields, andcts:field-word-query

Fields (in the field-word-query sense) don't relate to the indexes used 
for element-query. As the admin guide puts it, "You can use fields to 
create portions of the content that you might want to query as a single 
unit."

That phrase "single unit" is key: fields are flat buckets of words, and 
do not relate to the original XML structure. If you want to combine 
several elements in an structurally-indexed manner, add a new XML 
element that has the desired structure (Corb and RecordLoader each have 
features aimed at this area).
