Hello everyone,
I recently stumbled on this paper after Ishan shared it on LinkedIn:
https://github.com/0ctopus13prime/lucene-cyborg-paper/blob/main/LuceneCyborg_Hybrid_Search_Engine_Written_in_Java_and_C%2B%2B.pdf
.
This is quite impressive: this person did a high-fidelity rewrite of Lucene
in C
Thanks for sharing Adrien, this is really cool! It's neat that the
relative gains of Java vs C are quite a bit less than they were ~11 years
ago when I played with a much smaller subset of queries. Also, COUNT on
disjunction queries with Lucene Cyborg got slower. What a feat, to port so

SegmentReader::get_live_docs() returns null, so the code does not use
deleted documents. Of course this is not relevant if the original Lucene
Index is also without deletions, but you need to keep an eye on it.
