Acoustid Index ============== Acoustid Index is a "number search engine". It's similar to text search engines, but instead of searching in documents that consist of words, it searches in documents that consist of 32-bit integers. It's a simple inverted index data structure that doesn't do any kind of processing on the indexed documents. This is useful for searching in Chromaprint[1] audio fingerprints, which are nothing more than 32-bit integer arrays. [1] http://acoustid.org/chromaprint Reindexing from the Acoustid database: $ echo "COPY (SELECT id, acoustid_extract_query(fingerprint) FROM fingerprint) TO stdout DELIMITER '|' " \ | psql -U acoustid acoustid | ./fpi-import -d idx/ -c -o 1. Stop importing 2. UPDATE fingerprint_index_queue SET fingerprint_id = (SELECT max(id) FROM fingerprint); 3. Index the database 4.
