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.
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.
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.
Forget about console commands, Pickmybrain does not need to be installed as separate package and that is why you can use it even in shared hosting environments. If your web server supports PHP + MYSQL (or equivalent) and you know how to CHMOD some files, you are good to go!
PMB's Application Programming Interface allows you to implement the search feature in any way you wish. Select the right sorting mode, amount of results and field weightning dynamically while searching. See the API documentation here.
Fine-tune everything as you want! Pickmybrain comes with a web-based control panel that provides in-depth information for every one of the 20+ settings. See demo here.
Pickmybrain is a search engine designed for indexing databases and websites. PHP's PDO abstraction layer enables indexing of 12 different databases and thanks to PMB's web crawler indexing web pages is also possible.
If you are looking for a straightforward approach to implement a search feature for your database or website, look no further. Pickmybrain is easily installable even with the most rudimentary skills. The web-based control panel provides information and tips if something needs your attention.
Pickmybrain offers excellent performance even on big search indexes, thanks to compressed inverted index architecture.
Pickmybrain allows you to fine-tune every indexing-related setting and therefore optimize the search engine for your individual needs.
Combine the free search engine with the sentiment analysis plugin and use it as a data analytics tool for comparing opinions over multiple domains.
