Elasticsearch is a distributed, RESTful search and analytics engine that lets you store, search and analyze with ease at scale. It lets you perform and combine many types of searches; it scales seamlessly, and offers answers incredibly fast with search results you can rank based on a variety of factors. Elasticsearch can be used for a wide variety of use cases, from maps and metrics to site search and workplace search, and with all data types.

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.

A simple document management system (DMS). Documents and associated datas are stored in a single file. Keep all your documents in your pocket on your USB stick.

Uses alternate data streams to provide arbitrary tagging and searching of files within NTFS and other modern file systems supporting alternate data streams. Customisable vocabulary provides searchable standardised tagging system of file associations. Unlike most other file archiving systems, no additional database is required, and the system is robust, and persists file attributes irrespective of renaming / moving / copying / modifying etc. I would appreciate your opinions and suggestions / bugs etc.

A simple little engine to do fuzzy name & address searching. Helps improve data quality and avoids duplicate data entry.

Built in SWT. It indexes and searches a large number of text files for given keywords.

This project considers the problem of calculating primes as a sorting problem. It includes the most efficient tree-based sorting algorithm that is possible and shows that finding a new prime can be done by sorting the differences between the previous primes in the right way. Unfortunately it has turned out that going this way is even more slowly than trying to find primes by brute force. So it can only be used as a test with heavy load for the sorting algorithm, which can be used for sorting any kind of data. And as already mentioned, it's just the most efficient tree-based sorting algorithm that you can get. But furthermore this way of finding primes interestingly leaves a hard nut to crack for mathematicians: In very rare cases it finds numbers that are not primes. For all primes below one million this phenomenon arises in exactly two cases: 31213 which is 7 * 7 * 7 * 7 * 13 336141 which is 3 * 3 * 13 * 13 * 13 * 17 Who can explain, why?
