Looks like part of your message was truncated.

However, you don't need to know the existence of -psmatch2- as a
user-written module for Stata (or any other name that a user has given
their command) in advance of searching for it as the following link

Propensity matching -->
Propensity weighting -->

..the results of which hint at -psmatch- and various other results.

Google (and others Microsoft with Bing, Yahoo!) invest a lot of time
and money in developing search algorithms for their sites.  I would
rather see Stata Corp. spend their efforts on developing data
management and statistical routines than improving the search
algorithm, particularly when the tools that already exist can be used
to great effect to find what you are looking for within the relatively
small Stata-sphere.

As Nick pointed out this does hinge on the authors guessing at the the
likely keywords that others would use to search for.  In general there
would be a common thread to terms people would use when looking for
