A Sanskrit lookup would be awesomesauce. But it is hard!
Sanskrit itself is phonetically more complex than Pali, so the initial scope is intrinsically bigger. At the same time, the Buddhist Sanskrit texts are much more diverse linguistically than the Pali. They range from fairly close to classical Sanskrit to various degrees of Prakrit hybrids. Furthermore, the texts are not necessarily from a clean and highly edited source like the modern Pali texts. In a text like the Lokuttaravada Bhikkhuni Vinaya, for example, it is not at all uncommon to find the same word spelled differently in the same paragraph, let alone in different contexts. Finally, the number of texts is much smaller than Pali. Not to mention, of course, that our team knows Pali much better than Sanskrit.
