For **asymmetric semantic search**, you usually have a **short query** (like a question or some keywords) and you want to find a longer paragraph answering the query. An example would be a query like _“What is Python”_ and you want to find the paragraph _“Python is an interpreted, high-level and general-purpose programming language. Python’s design philosophy …”_. For asymmetric tasks, flipping the query and the entries in your corpus usually does not make sense.
