Returns each matching definition whole (the defining paragraph and every
sub-paragraph under it), first, marked kind='definition'. Matching
ignores case, hyphens, spacing, plurals, a trailing "means", and the
acronym 2.101 puts in a name, so 'service-disabled veteran-owned small
business concern', 'SDVOSB concern', 'COTS', 'commercial services' and
'contract means' all find their definitions. Other 2.101 paragraphs that
use the term (whole words only) follow as kind='mention', each naming
the definition it sits in.

When 2.101 doesn't define the term, the tool searches the rest of the
FAR (chapter 1), then the DFARS (chapter 2), for "<term>" means and
returns where it is defined, with the definition text, under
defined_elsewhere (for example 19.001 and 52.219-14 for 'similarly
situated entity'; 204.7301 for 'covered defense information'), plus
did_you_mean suggestions from 2.101.

term must be at least 3 characters. max_matches caps the number of
matches returned (default 20, max 100); definitions are never cut, and
truncated says whether mentions were left out.
