Create an API to call elastic search

[hubsmoke]

We have a Kibana instance at https://18.226.200.168:5601/
(send your IP address to Sina for whitelisting)

We need to call ElasticSearch to support filtering from the new UI

Features:

Proposed search entities: Author, Topic (in db as 'openalex concept' https://docs.openalex.org/api-entities/concepts), Year, Field, Keyword, Institution, Journal (source https://docs.openalex.org/api-entities/sources), Publisher

• Fuzzy search title
• Fuzzy search author
• Boolean search = union of AND filters across different entities, and OR filters within the same entity. Example: Author:Philipp Koellinger AND (institution=Vrije Universiteit OR institution=University Madison)
• 
• Sort by date (asc/desc)
• Sort by relevance (asc/desc)

Return paginated array of results that can power the search results UI with every field in the search result card
