Egothor is an Open Source, high-performance, full-featured text search engine written entirely in Java. It is technology suitable for nearly any application that requires full-text search, especially cross-platform. It can be configured as a standalone engine, metasearcher, peer-to-peer HUB, and, moreover, it can be used as a library for an application that needs full-text search.
Key features of egothor
* Written in JAVA for cross platform compatibility.
* New dynamization algorithm for fast index updating.
* Fully 64-bit kernel
* Queries can be solved in a parallel manner
* Able to recognize the most familiar file formats: HTML, PDF, PS, and Microsoft's DOC, and XLS.
* High capacity robot which supports robots.txt recommendation.
* The best compression methods are used, i.e. Golomb, Elias-Gamma, Block coding.
* Based on the extended Boolean model which can operate as the Vector or Boolean models.
* Universal stemmer that processes any language.
The engine implements a special algorithm that lowers demand for I/O operation during index updating. Other Open Source packages do not offer the same feature and use suboptimal solutions.
The engine may solve queries in a parallel manner since egothor 1.x. We are not aware of any other Open Source package that supports the same feature in its kernel.
The kernel is fully 64bit. There are not any other technical limits.
