Custom Search Engine
I have been working on my Google Custom Search Engine, you can see the actual results here. The GSE documentation is not very comprehensive, for example, I can’t find anything about AdditionalData tag, but it is used in one of the featured examples (same with timestamp attribute). It is not very hard to build your own CSE because almost all what we need we have in the control panel of each search engine, and also we can use advanced options to extend our engine. But I think the best way to build more interesting application is to use Custom Search Engine and Google Ajax Search API, however doing that, we have to
find a compromise between full control and quantity of results. I will try to take as much as I need from both CSE and Google Search API, but I don’t really know how this frankenstein will be look like.
