Usage
Here's a sample pre-built index on TREC Disks 4 & 5 to play with (used in the TREC 2004 Robust Track):
wget https://git.uwaterloo.ca/jimmylin/anserini-indexes/raw/master/index-robust04-20191213.tar.gz
tar xvfz index-robust04-20191213.tar.gz
Use the SimpleSearcher
for searching:
from pyserini.search import pysearch
searcher = pysearch.SimpleSearcher('index-robust04-20191213/')
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
