search - define and implement a generic search plugin

[rjrodger]

• same principle as seneca-entity, but for for seach
• no need for a special method api (like make$, list$ etc) - just seneca msgs
• @seneca/search - generic, in-memory - like mem-store- search quality does not matter
  • maybe just use something like: https://github.com/lucaong/minisearch
• provide implement plugins:
  • @seneca/search-awscs - for https://aws.amazon.com/cloudsearch/ - use the local simulations such as https://github.com/oisinmulvihill/nozama-cloudsearch
  • @seneca/search-elastic - https://www.npmjs.com/package/elasticsearch
  • @seneca/search-vespa - https://vespa.ai/ - NICE TO HAVE
  • @seneca/search-algolia - https://www.algolia.com/ - NICE TO HAVE
• good example of this idea:
  • https://github.com/senecajs/seneca-cache
  • https://github.com/senecajs/seneca-redis-cache
  • https://github.com/senecajs/seneca-memcached-cache
