Usage

As a quick start, use the SimpleSearcher for searching, with a pre-built index on TREC Disks 4 & 5 (used in the TREC 2004 Robust Track):

from pyserini.search import SimpleSearcher

searcher = SimpleSearcher.from_prebuilt_index('robust04')
hits = searcher.search('hubble space telescope')

# Print the first 10 hits:
for i in range(0, 10):
    print(f'{i+1:2} {hits[i].docid:15} {hits[i].score:.5f}')

# Grab the actual text:
hits[0].raw
