Open Source BSD Search Software

CLucene is a C++ port of Lucene: the high-performance, full-featured text search engine written in Java. CLucene is faster than lucene as it is written in C++.

turbovec is a Rust-based vector index with Python bindings for fast similarity search. It is built around TurboQuant, a quantization approach designed to reduce vector storage while preserving useful distance information. The project targets workloads where embedding search needs to be compact, efficient, and practical to integrate into Python applications. It avoids a separate training phase for the quantizer, which can simplify setup compared with systems that require codebook learning. TurboVec is useful for developers building retrieval, ranking, semantic search, recommendation, or AI memory systems. Its main value is combining Rust performance with a Python-facing workflow for modern vector search experiments and applications.

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.

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.

Career Ops is an open-source platform designed to help individuals manage their job search process with a structured, operations-style approach that treats career development like a pipeline. It provides a system for organizing job applications, tracking progress across different stages, and maintaining visibility into opportunities, much like a lightweight CRM tailored for job seekers. The project emphasizes clarity and accountability, enabling users to monitor applications, follow-ups, and outcomes in a centralized environment. It is typically built with modern web technologies, allowing for easy customization and self-hosting by developers who want full control over their data. Career Ops focuses on reducing the chaos and fragmentation that often comes with job searching by introducing a repeatable workflow that can be iterated and improved over time. It also supports the idea of data-driven job searching.

FreeAskInternet is a self-hosted search and answer application that combines web results with large language models. A local SearXNG instance sends queries to multiple search engines and returns a broader collection of sources. The backend crawls selected pages, supplies their content to a configured model, and streams a synthesized response to the chat interface. It supports several hosted model services as well as custom local backends such as Ollama and llama.cpp. The web interface is designed for desktop and mobile use and exposes the service only on the local machine by default. Docker Compose provides a straightforward deployment path without requiring a dedicated GPU. The project is still described as early-stage, and actual privacy depends partly on whether users select a local or external model provider.

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.

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

PanSou is a high-performance cloud-storage resource search API built around concurrent Telegram and plugin-based discovery. It searches multiple configured sources in parallel and aggregates links into a normalized result format. Supported link categories include Baidu, Aliyun, Quark, Tianyi, UC, 115, PikPak, Xunlei, 123 Cloud, magnet links, ED2K, and others. Results are ranked using source priority, freshness, and keyword signals. An asynchronous plugin system allows new search providers to be added without changing the core service. Memory and disk caching improve repeated-query performance, while optional JWT authentication can protect the API. PanSou is written in Go and can be deployed directly or through Docker and Docker Compose.

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.

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

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.

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)

sfbf (Search For Big Files) is a useful console application to search for largest files on file systems. It brings features such as : - Fast file search to locate largest files - Configurable search depth - Various output formats (txt, json, xml, html, csv) - Regular expression matching This project is licensed under the WTFPL (Do What The Fuck You Want To Public License, Version 2) Copyright © 2017 spypunk spypunk@gmail.com This work is free.

Aperture is a Java framework for extracting and querying full-text content and metadata from various information systems (file systems, web sites, mail boxes, ...) and the file formats (documents, images, ...) occurring in these systems.

Sgrep (sorted grep) is a much faster alternative to traditional Unix grep when searching large files, because sgrep searches sorted input files using a fast binary search to find matching lines.

Kato is an approach to bring the work done on software agents out of academia and into the public arena. Developers can create agents as easily as they can Drupal modules.

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.

Power searching without the pain. Perform powerful desktop searches without having to index your system using regular expressions. Graphical equivalent to grep. Fork have new features like displaying context of files and "Open With" menu in Linux with KDE.

Puggle is a graphical desktop search engine written exclusively in Java. It provides full text and metadata search over files, folders, music, photos, web pages and more that are stored locally on your computer.

Syracuse is the search engine which powers SourceForge.net's search and Software Map features.

The findstr is searching the words in the text and binary files in several codepages. The famouse 'grep' is very slow and get a lot memory for large binary files without ends of lines - findstr is fast and light, but it doesn't use regular expressions.

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

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.
