Fast-Forward Indexes

Fast-Forward indexes combine the efficiency of lexical sparse retrieval methods with the effectiveness of semantic dense retrieval methods. The main features are:

• Fast CPU-based ranking
• Memory- and disk-based indexes
• Index compression via sequential coalescing
• Heuristic early stopping technique to limit number of index look-ups
• PyTerrier integration

pip install fast-forward-indexes
