It should be great if DA supports case sensitive queries. I’m learning ConTeXt – a LaTeX-like macro for TeX – and I have to search the web for solutions, but “context” is such a common word that the search results are almost useless until I add “tex” in my queries. Sure I could setup a crawler on mailing lists but it’s far from being a good solution.
I think that DA should detect the type case and execute case sensitive queries if the search string contains uppercases. Search engines and metacrawlers are case insensitive but DA can search inside the text pages and filter results by being case sensitive.
