Boss: search box
A search box should find 'harbour' articles even when the user types 'harbur'. Full-text search comes first; trigram similarity is the fallback when it finds nothing. The indexes already exist.
task
One query for the term 'harbur' (a typo): the top 5 article ids by full-text rank, and only when full-text finds nothing, the top 5 by trigram word similarity on the title. Stay within 1.5 times the reference buffers.
