"site:www.investorvillage.com", then add your search terms. So, for example:
"site:www.investorvillage.com watsonncrick" then add the intext: operator, with the Boolean AND like so:
"site:www.investorvillage.com watsonncrick AND intext:cns". That search
yields five results. Maybe not great, but it does do it.
I don't think that google supports "+" as an operator. When I tried adding it to searches, the results disappeared. Appears it is interpreted as a character not an operator.
I believe the IV search function also supports Boolean AND/OR. You may be able to refine your results that way.
