A Comedy of Errors: My Amateur Search Library vs. Elasticsearch

The author compares their Pandas-based full-text search library, SearchArray, against Elasticsearch using the BEIR benchmark. The results are humbling: SearchArray significantly underperforms Elasticsearch in all aspects. The article delves into the reasons, highlighting optimizations in production-ready search engines like Elasticsearch, such as the WAND algorithm and efficient inverted indices. SearchArray's lack of these optimizations leads to poor performance. The author concludes that SearchArray is suitable for prototyping on smaller datasets, but not for large-scale retrieval systems.
