Index support for regular expression search

Date: 2012-10-25
Time: 14:40 - 15:30
Room: Vltava
Level: Advanced

Regular expressions (regex) are powerful tool for text processing. When dealing with large string collections it's important to search fast on that collections (i.e. search using index). Indexing for regex search is a quite hard task. This talk presents novel technique (and WIP patch for PostgreSQL implementing it) for regex search using trigram indexes. Proposed technique provides more comprehensive trigram extraction than analogues, i.e. higher performance.
