A P2P application that shares raw information between peers. Using a altered G2 protocol (called Z1) to search data within files/databases by means of file and database specific providers. Web services nodes may in future extend the Z1 network beyond des

Knowledge management tool which is primarily designed for pdf files. The tool will let the documents get tagged either automatically or manually. Within the pdf archieve, a user will be able to retrieve desired documents quickly.

Locate zip and jar files that content matches a pattern. Also useful for finding class files in jar files.

Find files within other ZIP JAR WAR EAR files. Search recursively for file names or search strings. This Java based utility can save you time when you wonder in which jar or ear file a particular class is defined.

A utility to recursively search for files on the file system including zip, ear, war, jar, rar archives.

zoekt is a fast, scalable code search engine written in Go that builds compressed indexes (shards) for source repositories and serves low-latency regex and substring queries. It optimizes for developer workflows: refresh indexes from Git, search across many repos instantly, and jump into hits with surrounding context and file navigation. The indexer uses efficient n-gram dictionaries and posting lists to keep query latency low, while storing metadata (branch, language, repo) for precise filtering. A built-in web UI and JSON API enable both interactive exploration and integration into editors and other tools. It supports ranking heuristics such as path weighting and symbol awareness to surface likely matches first, even in monorepos. Incremental and parallel indexing let it keep up with active codebases, making it suitable for both local deployments and multi-tenant service setups.

ack.vim is a Vim plugin interface to the ack command-line tool, providing fast, grep-like search functionality directly within Vim. It displays search results in a split window and supports navigation through them seamlessly. This plugin was designed as a Vim frontend for the programmer's search tool ack. ack can be used as a replacement for 99% of the uses of grep. The plugin allows you to search with ack from within Vim and shows the results in a split window. But here's a little secret for the Vim-seasoned: it's just a light wrapper for Vim's grepprg and the quickfix window for match results. This makes it easy to integrate with your own Vim configuration and use existing knowledge of core features. It also means the plugin is flexible to use with other search tools.

ack2 is a programmer-centric search tool written in Perl that serves as a smarter, faster alternative to grep for source trees. It defaults to searching only relevant files while skipping build artifacts, VCS directories, minified bundles, and other noise, which dramatically reduces false hits. Filetype filtering is first-class: you can target languages by name (--perl, --python, --js) or define your own groups, and ack maps common extensions automatically. Results are colorized with context options, PCRE regular expressions are supported, and output is tuned for quick scanning across many files. The tool respects .gitignore and its own ignore mechanisms, and it offers sensible defaults that require minimal flags for day-to-day use. By optimizing for developer workflows rather than raw POSIX compatibility, ack2 helps you navigate large codebases with less typing and less cognitive load.

bnf2xml a simple BNF parser that takes text as input, searches according to a BNF query file, and outputs text marked up by the xml labels that show context. bnf2xml is as simple to use as any text binary ie, awk(1) grep(1). bnf2xml does not require C API because it outputs simple xml labeling. README is visible on file dl page. EXAMPLE: $ echo "hi" | bnf2xml patternfile <word><alph>h</alph><alph>i</alph></word> or <gas>hydrogen iodide</gas> patternfile says how to find needle in haystack and what to show, ie: <alph> ::= a | b | c | d ... <word> ::= <alph>+ bnf2xml is a top down recursive parser. Unlike buttom up parsers like gcc(1) or some top downs, bnf2xml is completely unambiguous / resolves ALL conflicts. Slower on ave. for parsing C or than sed(1) for simple searches. Far easier than using flex/C to create a parser. caveate: I do not suggest it's worth while to make a new gcc(1) using bnf2xml. bnf2xml an nth BETA release, but no complains yet.

A UNIX style content indexer. Works like good old "locate" and provides functionality similar to tools like Google Desktop.

cgrep provides many of the features of grep, egrep, and fgrep with greatly enhanced performance along with many additional features, one of which is the ability to output the context (surrounding lines) of the matching lines.

Clucened is a project to build a daemon around CLucene, which is a C++ implementation of the Lucene search engine. This is *not* the CLucene project, but is a separate project to write a generic daemon based on CLucene.

This small C# (mono or MS.NET 3.5 required) console program generates text or html output which lists directories and files. Copies of directory or file names will be marked in HTML output. I use it to find files in a messy company network.

Xapian index viewer Source code: http://github.com/dualword/dualword-index/

This is a simple C++ program made to extract the full-size images from a "Enlarged Pictures" gallery, when a listing has multiple pictures. This was primarily developed for people who want to read dates of collectors items or ID codes on certain items where the "enlarged" gallery still provides, not enough size. Disclaimer: This project was not created for people to steal other people's listing pictures to use for themselves.

e-Book Keeper is an easy to use e-Book collection management utility for users who possess many e-Books in varying formats about varying subjects and would like to keep them organized easily and cut the amount of duplicates.

Search engine with web-interface,which can be installed on Linux and Windows machines, and disturbed across LAN to decrease scan time.

# fileLocator is a simple tool BUILD using Python and PyQt4, and I have Build two simple version for this tool : == #1. fileLocator console application, for those who love command line applications. #2. fileLocator-GUI application, that is very easy to use and another advantage of this application is that, This is a Portable application, means you can just download and put it anywhere and use it, No need to download and Install and install other dependencies. This will work just fine even if you use this on any computer from USB drive/Memory card. # How you can look for files faster than ever # In this application I have made two new changes, if you made use them properly then you can think that it has amazing speed. # first you should use Disk Index file and by default I have turned off this option, Because you better know that when you should use this option. # If you are going to use Disk Index file for your defined path then You should keep one thing in mi

A command line tool to get information about files on your file system thanks to SQL queries. It is able to point quickly broken symbolic links, hard links and sparse files. It targets Unix but it should run on any system where Perl is available.

find extension tool : list all extensions of a directory

This project is a tool to detect file types by signatures and mime types. It uses hash tables to make the detection of a file type as fast as possible. The signature and mime types lists are stored at simple user-friendly files. This file type detector supports a lot of formats (image, archive, text, documents, audio, video, fonts and others). It also includes Microsoft OLE compound file types. The detector's algorythm has special features to detect text file types like (HTML, XML, JSON, etc.) and text file UNICODE charsets by using their BOMs (Byte order marks). Its small simple interface can be used at the most popular platforms.

gDiscoverer is a search tool, that is providing a inexact search, that means, that you could type in "lunex" and get "Linux" as result.

Search for files and folder.

Provides remote searching to Google Desktop Search
