Using Google Better. Ex Christian Homeschooling

I'm trying to master some of the basics of being a better Google user. For instance, I keep forgetting how to search a specific site for infomation. Here is it, I just looked it up:

Search within a specific website (site:)
Google allows you to specify that your search results must come from a given website. For example, the query [ iraq site:nytimes.com ] will return pages about Iraq but only from nytimes.com. The simpler queries [ iraq nytimes.com ] or [ iraq New York Times ] will usually be just as good, though they might return results from other sites that mention the New York Times. You can also specify a whole class of sites, for example [ iraq site:.gov ] will return results only from a .gov domain and [ iraq site:.iq ] will return results only from Iraqi sites.

So to query Time4Learning.com for anything about christian homeschoolers:   [ christian homeschool site:time4learning.com ].

I'll try it....Found it:  Christian Homeschooling.  I find this description unsatisfactory. I'd like it to be extended to cover:

- the options for not using or excluding the science or social studies

- how to handle the "teachable moments" that a T4L includes

- the pros & cons for a Christian to use a secular curriculum

- the detailed Christian homeschool discussions  on the parents forum about these topics.
