GLIMPSE 4.18: searching entire file systems (http://webglimpse.org/) (http://glimpse.cs.arizona.edu/) For installation instructions, see README.install Glimpse is a very powerful indexing and query system that allows you to search through all your files very quickly. It can be used by individuals for their personal file systems as well as by organizations for large data collections. Glimpse is also the basis of WebGlimpse, which provides search for web sites, and it is the default search engine in Harvest (see below). Glimpseindex, which you run by saying "glimpseindex DIR" builds an index of all text files in the tree rooted at DIR. (e.g., glimpseindex ~ indexes all your files.) With it, glimpse can search through all files much the same way as agrep (or any other grep), except that you don't have to specify file names and the search is fast. For example, glimpse -1 unbelievable will find all occurrences (in all your files!) of "unbelievable" allowing one spelling error; glimpse -F mail arizona will find all occurrences of "arizona" in all files with "mail" somewhere in their name; glimpse 'Arizona desert;windsurfing' will find all lines that contain both "Arizona desert" and "windsurfing". Glimpse supports three types of indexes: a tiny one (2-3% of the size of all files), a small one (7-9%), and a medium one (20-30%). The larger the index the faster the search. Glimpse supports most of agrep's options (agrep is our powerful version of grep, and it is part of glimpse) including approximate matching (e.g., finding misspelled words), Boolean queries, and even some limited forms of regular expressions.
