Debanjum Singh Solanky 989526ae54 Use a more accurate model for symmetric semantic search
- The all-MiniLM-L6-v2 is more accurate
  - The exact previous model isn't benchmarked but based on the
    performance of the closest model to it. Seems like the new model
    maybe similar in speed and size

- On very preliminary evaluation of the model, the new model seems
  faster, with pretty decent results
