The Theology Portal gives access to resources on the net. 2 different tecniques are used to perform automated selection of resources.I've run a few searches on it myself and it seems pretty impressive -- try both the Quick Search and the Advanced Search for different results:
In Portal 1 a direct search in Google is performed. The search is delimited by the portal, so that the actual search is a "search within result" in a existing search set.
In portal 2 a search is performed in a delimited number of resources on the net, selected by experts.
The Theology Portal covers the subject Christian Theology, defined as the academic discipline carried out at universities in Europe.
I am going to write to the owner to see if they will grant permission for me to add this search to the All-in-One Biblical Resources Search.
