st: Is PSMATCH2 able to perform exact match?

["Shahraz, Saeid" <saeid_shahraz@harvard.edu>]

Hi,
I wonder if psmatch2 performs exact match. I apply psmatch2 by writing a
code that looks like: psmatch2 a b c, out(x)logit common
According to psmatch2 stata help after writing stata codes like what I
wrote above you will get a one-to-one match results. I wonder if this
means an exact match or still psmatch2 tries to match the nearest
possible control to your case given the match covariates.
I appreciate any feedback that helps me figure out this.
Thanks
saeid
