Search page wont load in Vercel

[stscoundrel]

Seems Vercel (at least in free tier) has some limitations as to how large dataset of single page can be. Next.js will happily build the page & work with it, but Vercel seems to block it.

Alter search page to:

• Handle search service portion in api route
• Only handle search & criteria selection in frontend

This should offload the json dataset to backend and keep Vercel happy. Frankly, it is also reasonable when the dictionary dataset is this large.
