Proposal - use &level=X
where X is the level but also number of digits. This uses the terminology that NAICS itself uses to describe each level. (http://www.bls.gov/sae/saewhatis.htm)
minimum of X is 2. Max of 2 is 6. The user can individually specify level by saying &level=2
or &level=5
, etc.
User can also specify a level range, e.g. &level=3-5
.
e.g. only 3-digit codes, or min of 4 digits / max of 5.
