Full-text searching

BM25 ranking alone is so old-school, that is why PMB offers a proprietary phrase proximity scoring algorithm that works together with the BM25 ranker. Partial matches are also supported with custom, dynamically calculated scores.

Sentiment Analysis

When searching by relevance is not enough anymore, PMB offers a word-class sentiment analysis plugin, which allows you to search and sort results by polarity of opinions. Learn more here.

Integrated PDF support

PDFs are the today's number one choice for easily accessible written content on multiple platforms. Forget about messing with third-party PDF libraries - PMB provides you an integrated and hassle-free solution for indexing your PDF-documents.

Easy installation
