Background
The MVP of hybrid search (semantic and lexical) shows lexical results at the top of search, and semantic below. In the current Android app, if you search for a complex query, you often receive no results. With the prototype, sometimes there are situations where we only have semantic results to show users. This is happening for 2/5 of the sample queries in Greek
Example
If we search Πότε ο Πλούτωνας έπαψε να θεωρείται πλανήτης (When did pluto stop being a planet) in our current app experience, we get no results
If we tap on the first suggested query Πότε ο Πλούτωνας έπαψε να θεωρείται πλανήτης (When did pluto stop being a planet) on the semantic search onboarding screen, we see:
Requirements
- Add "No article title matches this query" toast when there are no lexical search results
