The twelve nidanas are defined elsewhere. And the fact that they are defined elsewhere is quite interesting. The Buddha never said “twelve nidanas”. The Buddha did talk about dependent origination in SN12.1
In fact, the term dvādasanidānāni, which is the suggested Pali translation of “twelve nidanas”, does not show up in SuttaCentral search. How wonderfully interesting!
In the blurb for SN12.1, Bhante Sujato kindly and clearly introduces the twelve without using nidana and plainly states without obfuscation:
The famous twelve links of dependent origination are spelled out
Furthermore, when one compares SN12.1 with the stock 12 nidanas, they are a bit different. Scholars have noted that
According to Schumann, the twelvefold chain is a later composition by monks, consisting of three shorter lists. These lists may have encompassed nidana 1-4, 5-8, and 8-12. The progress of this composition can be traced in various steps in the canon.
In other words “twelve nidanas” is a bit…“woke”.
On a separate note, @Aminah, I’ve added a new feature proposal to v1.0 that would provide a link to Google for SCV searches without search results. I think this could be a solution for many searches that are abhidhammic in nature, i.e., for Buddhist terms never uttered by the Buddha. I also think your own suggestion of hashtags in search (i.e., #bodhisattva) is an excellent way to build bridges of understanding. The hashtag solution may not apply well to phrases such as “twelve nidanas”, unless one would allow #twelveNidanas? I am not a tweeter, so I can’t speak to the efficacy of multi-word tweets.
