Suggest a free alternative to Custom Search JSON API

[suvnshr]

Currently, the project uses Google's Custom Search JSON API for generating search results. But on the free plan, the current API provides only 100 search queries per day and with billing enabled 10,000 queries per day max :woman_shrugging: :man_shrugging: for more details on its pricing go here.

We are looking :eyes: for a free alternative to this so that users can do more searches per day. Google also provides a Custom Search Site Restricted JSON API using which we can make unlimited queries :lock: but it can only search some specific sites only.

Suggestions are welcome :bowing_woman: :bowing_man:
