The ez_search library

ez_search is a library for indexing files and searching content with rexgexps. It creates a dababase of two files (one with the raw files, one with the index) on disk. The database can then be searched for occurrences of regexps, using either [Re] or [Str]. Direct string matching and case insensitive searches are also supported. Ez_search can [mmap] the database to decrease its memory footprint, and [Parmap] to search the database on multiple cores in parallel (in which case the results may overlap). It also provides a "context extraction" feature to display lines above and after an occurrence.
