I've been trying to make sense of Google Scholar searches. I'm obviously
missing something basic. Here are two searches on www.google.com:
sas - gets 68M hits
sas OR spss - gets 74.3M hits. A bigger number as "OR" would imply.
But when I do the same searches on scholar.google.com, here's what I
get:
sas - gets 4.6M hits
sas OR spss - gets 1.65M hits
How on earth can an "OR" get you less??
Because the search for SAS alone stems the words so you get hist on SA
alone (SAS obviously (!) being the plural of SA). As you will see from
the first few hits (hint: the matched word is highlighted in bold).
With the OR you don't stem (weird but true). Put quotes around the
single search term to avoid (some of) the stemming:
SAS - 4.62M
"SAS" - 1.62M
"SPSS" - 0.635M
"SAS" OR "SPSS" - 1.52M
It is obviously still not right, but closer. Happy reading of the
articles by D. Sas, S.A.S. Eddington, etc.
Any follow-ups probably belong on a different mailing list - I think
there are forums for Google search.

This one is nice too. You can see that the bump in the autumn semester
for R is replacing the one for Matlab. Then in the spring semester
Matlab stays high but R drops. And both the US and India always have a
very large search index, whereas the rest of the world is essentially
worthless. Which leads me to the conclusion that : 1) The results are
probably coming from google.com, excluding local versions, and 2) in
the US (and India), statistics is mainly taught in the autumn
semester. Given the fact that daylight has a beneficial effect on the
emotional well being, the impopularity of statistics is likely caused
by unfortunate scheduling.
Forget Excel. Google rocks! ;-)

Once you go the phrase route, you gain precision but end up with zero
counts on various phrases. I avoided that by combining them with "+"
to
get enough to plot. The resulting graph shows SAS dominant until
mid-2006 when SPSS takes the top position, followed by R, SAS, Stata
in
order:

I see that there's a car, the R Code Mustang, that adding "for" gets
rid
of.
Thanks for getting me back on a topic that I had given up on!

Google
Insights for Search - http://www.google.com/insights/search/#
Every person using a software like R, SAS, SPSS needs first to
learn
it. So probably he make a web-search for a manual, a tutorial, a
guide. One can measure the share of this kind of serach query.
This kind of results can be useful to determine trends of
"popularity".
Example 1: "R tutorial/manual/guide", "SAS tutorial/manual/guide",
"SPSS tutorial/manual/guide"

Some example are cross-software (learning needs - Example1), other
can
be biased by the tarditional use of that software (in SPSS usually
you
don't manipulate graph, i think)
