Power searching on your desktop without the pain. Perform powerful desktop searches without having to index your system using regular expressions. Graphical equivalent to find/grep. Available for Windows (JAVA) and Linux (Gnome & KDE) and easy to translate into your locale.

Search and replace operations on file content accross multiple files. Recursive operations within entire directory trees. FAR comes with support for regular expressions (regex) over multiple lines, automatic backup and various character encodings. Run grep like extractions to condense or rearrange sources, or perform bulk file renaming.

Laravel Scout provides a simple, driver-based solution for adding full-text search to your Eloquent models. Once Scout is installed and configured, it will automatically sync your model changes to your search indexes.

phpMorphy is morphological analyzer library written in pure PHP. Currently supports Russian, English and German languages.

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.

OpenSearchServer is a powerful, enterprise-class, search engine program. Using the web user interface, the crawlers (web, file, database, etc.) and the client libraries (REST/API , Ruby, Rails, Node.js, PHP, Perl) you will be able to integrate quickly and easily advanced full-text search capabilities in your application: Full-text with basic semantic, join queries, boolean queries, facet and filter, document (PDF, Office, etc.) indexation, web scrapping,etc. OpenSearchServer runs on Windows and Linux/Unix/BSD.

CRGREP searches for matching text in databases, various document formats, archives and other difficult to access resources. A command line tool for name and content text matching in database tables, plain files, MS Office documents, PDF, archives, MP3 audio, image meta-data, scanned documents, maven dependencies and web resources. CRGREP will search resources within resources of any arbitrary combination or depth, so text within a document within a zip archive, and so on. Here you will find binary downloads and discussion (https://sourceforge.net/p/crgrep/discussion/) . The actual development and issue tracking can be found here: https://bitbucket.org/cryanfuse/crgrep

mairix is a tool for indexing and searching email messages stored in Maildir, MH, or mbox folders.

FTimes is a forensic system baselining, searching, and evidence collection tool. Its primary purpose is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis.

Full text search engine - console tools and GUI frontends for users, program components and libraries for developers. Cross-platform, portable (Win32/64, .NET, Linux). Extensible architecture. Morphology of natural languages (English, Russian and French)

disk manager is a CD/DVD archiving tool. It storys the directory contents of any media so you can search it later. Its also designed as file explorer which makes it easy to find big files. Windows Version supports native file context menus.

This is a autorun menu for cd's. It link a name with a file and a short description. It can execute/open files, copy directories, execute commands, etc and it is really easy to use. (Spanish)

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.

Enhanced version of the standard Unix strings(1) program which uses language models for automatic language identification and character-set identification, supporting over 1400 languages, dozens of character encodings, and 4800+ language/encoding pairs.

SCAN (Smart Content Aggregation and Navigation) is a universal semantic content aggregator. It combines search, text analysis, tagging and metadata functions to provide new user experience of desktop navigation and document management.

This is a python based UI application that can rename a part of a set of files inside a directory based on the provided regular expression. This gives a lot more flexibility compared to other renaming files since it used grouping principle. This had two level of applying the rename, first stage shows who it will be when you rename it, if you are fine with the change you can make it permanent by clicking commit. This avoid the risk of file getting corrupted. To rename all .py file to .pyc is as follows: Search for Regex: (.py)$ Rename using this regex: .pyw

E-Nature CD/DVD Archiver lets you easily read all files on any data CD/DVD to a local database. With the integrated search function you can search for files stored on any previously added DVD or CD in your collection.

Bible Concordance generator and viewer for UNIX/Linux/Cygwin, written in C. Supports multiple word searches using boolean operators and Reverse Polish notation. Unlike printed concordances, shows complete verse, and in context.

A Python/Tk gui for find and grep. FindEmAll is, compared with other similar file search tools, fast and resource-efficient and independent from any desktop environment (no Gnome or KDE libraries required).

A catalog application for various media types - CD, DVD, NetDrives, USB flash keys, etc. It can import data from famous WhereIsIt Windows applicaion. In a word this is a try to make a WhereIsIt-like application for Linux.
