DataparkSearch Engine 4.53: Reference manual
Prev |  | Next

# Chapter 1. Introduction

DataparkSearch is a full-featured web search engine. DataparkSearch consists of two parts. The first part is an indexing mechanism (the indexer). The indexer walks over hypertext references and stores found words and new references into the database. The second part is a CGI front-end to provide the search service using the data collected by the indexer.

DataparkSearch was cloned from the 3.2.16 CVS version of mnoGoSearch at 27 November 2003 as DataparkSearch 4.16. The mnoGoSearch's first release took place in November 1998. The search engine had the name of UDMSearch until October 2000 when the project was acquired by Lavtech.Com Corp. and changed its name to mnoGoSearch.

The latest change log of DataparkSearch can be found on our website.
