  • + indicates a search term must be found
  • and - excludes it
• Multiple conditions can be combined with logical operators
  • OR
  • AND
• Also you can separate by comma "," multiple requests for a parallel processing as below:
  • "(+Bitcoin -Luna) OR (+ETH), (+crypto)"
  • Will return matches to data that hit Bitcoin or ETH but not Luna for the first query, and crypto for the second
  • Amount of sub-queries is not limited and is executed in parallel

Topic embedding search engine

Topic syntax

• In contrast with keyword based search, topic syntax allows to query data in a fuzzy way. It works the best when 2-5 words describe some wider concepts, examples:
  • "NASDAQ technology index"
  • "Airline travel demand"
  • "Energy disruptions in Europe"
• Such queries will include related concept
  • for "NASDAQ technology index" it might also consider terms as "Dow Jones", "FAANG", "FTSE" etc.
  • exact structure depends mostly on how topics co-occur together
  • intuition behind is that NASDAQ is US tech stock index, but if data contains strong signals from FTSE, a British blue chip index, or Dow Jones, less tech heavy index, this will also have an impact on query of interest
  • to reflect changing world situation, underlying models are constantly re-trained making sure relations are up-to-date

from adase_api import query

q = "inflation rates, OPEC cartel"
df = query.load_frame(q, engine='topic', start_date='2022-01-01')
df.unstack(2).tail(10)
