ALTSE is an alternative search engine technology.

It can index up to a couple million Web sites.

A search engine is a program designed to help find information stored on a computer system such as the World Wide Web, or a personal computer.

The search engine allows one to ask for content meeting specific criteria (typically those containing a given word or phrase) and retrieves a list of references that match those criteria.

Search engines use regularly updated indexes to operate quickly and efficiently. Without further qualification, search engine usually refers to a Web search engine, which searches for information on the public Web.

Other kinds of search engine are enterprise search engines, which search on intranets and personal search engines, which search individual personal computers.

Some search engines also mine data available in newsgroups, large databases, or open directories like DMOZ.org. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically.

Most web sites which call themselves search engines, are actually front ends to other search engines owned by other companies. The typical user will often not know which underlying search engine they are using.

MKSearch provides a Web metadata spider and search engine.

MKSearch is a metadata search engine that indexes structured metadata in Web documents instead of free text in the document body.

The data acquisition system conforms to the Dublin Core metadata in HTML recommendations, and supports other application profiles, such as the UK e-Government Metadata Standard.

It also indexes native RDF formats, including RSS 1.0. The system has five major components: a Web crawler, an HTML document validator and formatter, a set of custom indexers, an RDF storage and query system, and a public query interface, provided through a standard servlet container.

System composition

The MKSearch system is composed of several other free software components. Further details are provided in the MKSearch development plans.

JSpider
JSpider is a Java Web crawler engine that has pluggable interfaces that can be used to add custom processing and content handling. MKSearch uses custom SAX-based content handlers for extracting metadata from Web documents.

Sesame
Sesame is a set of RDF processing and storage APIs and applications that includes RDF data query facilities. MKSearch uses Sesame to store indexed metadata in RDF format and to search the repository via the public query interface.

JTidy
JTidy is a utility for correcting common HTML markup errors and is used to convert HTML documents to XHTML so they can be processed using SAX.

Sethi Search Utility provides a simple command line utility to submit a search to Google, Yahoo!, or MSN.
Sethi Search Utility is a simple command line utility to submit a search to Google, Yahoo!, or MSN and show the (text) results on standard output. Support for several search engines is included.
Its currently in serious need of a re-write, especially to avoid scraping and become a good engine using the search APIs provided.
Enhancements:
- The Google configuration was updated.

Ethics Search Protocol in short ESP is an XML-based protocol for search engines that is designed to allow people to express specific ethical requirements when performing searches.
Consumers seldom get the chance to communicate ethical requirements because the proper communication channel does not exist. This project has the goal to offer an open source specification and implementation for that missing communication channel.
Enhancements:
- Changes were made to Category, OrganizationSearchParameters, SearchProfile, and Community.
- PolicyReference complements PolicyStatement.
- EvaluationScheme complements VotingScheme.
- The Envelope type was removed.
- The documentation was improved.

Absolut Engine is a news publishing system. It features three-layer access (admin/chief/editor), article posting, editing, and deleting. Absolut Engine includes a powerful image managing tool, a file manager, and a related articles manager.

Rich text editing is provided via a built-in WYSIWYG editor that produces XHTML 1.0 Strict-compliant code. Absolut Engine is easy to extend via module functionality. The provided modules include Discussions, Surveys, RSS Feed, Search Engine Optimization (static/clean URLs), and a message system for better communication between users.

Absolut Engine produces Web-standards-compliant valid and accessible XHTML 1.0 Strict and CSS semantically-correct code.

Xapian is an Open Source Probabilistic Information Retrieval library, released under the GPL. Xapian iss written in C++, with bindings to allow use from other languages (Perl, Java, Python, PHP, and TCL are currently supported; Guile and C# are being worked on).
Xapian is designed to be a highly adaptable toolkit to allow developers to easily add advanced indexing and search facilities to their own applications.
If youre after a packaged search engine for your website, you should take a look at Omega, which is an application we supply built upon Xapian. But unlike most other website search solutions, Xapians versatility allows you to extend Omega to meet your needs as they grow.
Main features:
- Free Software/Open Source - licensed under the GPL.
- Highly portable - runs on many Linux, MacOS X, many other Unix platforms, and Microsoft Windows.
- Written in C++. Perl bindings are available in the module Search::Xapian on CPAN. Java JNI bindings are included in the xapian-bindings module. We also support SWIG which can generate bindings for 13 languages. At present those for Python, PHP4, and TCL are working. Guile and C# are being worked on.
- Ranked probablistic search - important words get more weight than unimportant words, so the most relevant documents are more likely to come near the top of the results list.
- Relevance feedback - given one or more documents, Xapian can suggest the most relevant index terms to expand a query, suggest related documents, categorise documents, etc.
- Phrase and proximity searching - users can search for words occuring in an exact phrase or within a specified number of words, either in a specified order, or in any order.
- Full range of structured boolean search operators ("stock NOT market", etc). The results of the boolean search are ranked by the probablistic weights. Boolean filters can also be applied to restrict a probabilistic search.
- Supports stemming of search terms (e.g. a search for "football" would match documents which mention "footballs" or "footballer"). This helps to find relevant documents which might otherwise be missed. Stemmers are currently included for Danish, Dutch, English, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish.
- Supports database files > 2GB - essential for scaling to large document collections.
- Platform independent data formats - you can build a database on one machine and search it on another.
- Allows simultaneous update and searching. New documents become searchable right away.
As well as the library, we supply a number of small example programs, and a larger application - an indexing and CGI-based application called omega:
- The indexer supplied can index HTML, PHP, PDF, PostScript, and plain text. Adding support for indexing other formats is easy where conversion filters are available (e.g. Microsoft Word). This indexer works using the filing system, but we also provide a script to allow the htdig web crawler to be hooked in, allowing remote sites to be searched using Omega.
- You can also index data from any SQL or other RDBMS supported by the Perl DBI module. That includes MySQL, PostgreSQL, SQLite, Sybase, MS SQL, LDAP, and ODBC.
- CGI search front-end supplied with highly customisable appearance. This can also be customised to output results in XML or CSV, which is useful if you are dynamically generating pages (e.g. with PHP or mod_perl) and just want raw search results which you can process in your own page layout code.
Enhancements:
- This release adds support for spelling correction and synonym expansion.
- Some Btree tables are now optional, so opening a database is slightly quicker.
- The Xapian::NumberValueRangeProcessor class has been reworked to fix a design flaw.
- A few bugs have been fixed.
- Performance was improved in several cases.
