Free search engine optimization software for linux

iSearch engine project is an internal web site search engine.
Built to run as a CGI module, iSearch performs a searching for one or more character sequences ( terms ) within documents in a web site, without the needing of external indexing and filtering tools, like, for example, a database engine.
iSearch performs a real time elaboration of HTML documents in a web site, every time it is invoked. Documents are found, filtered from unnecessary parts, like HTML tag, and then inspected searching for the input terms.
iSearch acts under the directives set in its configuration file. You can set one or more starting search path, exclude file or directories from scanning, set your own output templates, and so on.
So if you want to add an internal search engine in your web site, iSearch is one of your possible solutions.
iSearch is written in C and the source code is based on Yed technology.
Main features:
- iSearch is a CGI module written in C, available for both GNU/Linux and Windows environment.
- iSearch latest release has been developed and tested within an Apache HTTP server. OS involved are Slackware GNU/Linux and Windows XP SP2, both on a i686 architecture.
- When invoked, iSearch scans recursively directories in a web site extracting files so-called documents. In every document extracted, iSearch performs a filtering to delete unnecessary information, like HTML tags. Then, the pure resulting text is inspected searching for the characters sequences received in input, so-called terms.
- A term can be a single word, but also a sequence of words enclosed with character "; in this latter case, the sequence will be treated as a single term ( i.e. "sowing the seeds of love" ).
- All documents containing all the terms will be output according to user templates and related environment.
- All terms are matched in boolean AND mode: only a document containing all terms is considered as a matched document.
- All terms are matched in case-insensitive mode.
Enhancements:
- The ID Input parameter is now optional.
- If omitted, it defaults to the first < root > element of the configuration.
- Handling of eventual error explanation string was added in displaying error templates, through the new token "%det".
- Its now possible to search for strings enclosed with quotation marks (").
- The source code has been totally reorganized.
- The < replace > element was added in the configuration file.
- This element contains a list of strings to replace or cut from documents to inspect.

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.

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.

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.

Javascript Search Aggregator allows you to perform all of your Web searches from one place.
You can create many categories of searches such as work and fun and customize search engines for your specific needs.
Javascript Search Aggregator remembers the last query and state of the tabs and works on any browser with JavaScript support.
Enhancements:
- Do not load last selected engine on first load

WWW::Search::Nomade is a Perl class for searching Nomade.

SYNOPSIS

use WWW::Search;

my $oSearch = new WWW::Search(Nomade);

$oSearch->maximum_to_retrieve(100);

#$oSearch ->{_debug}=1;

# Create request
$oSearch->native_query(WWW::Search::escape_query("cgi"));

# or Make an international search (on google db)
$oSearch->native_query(WWW::Search::escape_query("cgi"),
{ opt => 1 });

print "I find ", $oSearch->approximate_result_count(),"n";
while (my $oResult = $oSearch->next_result())
{ print "Url:", $oResult->url,"n","Titre:", $oResult->title,"n"; }

This class is an Nomade specialization of WWW::Search. It handles making and interpreting Nomade searches http://www.Nomade.fr, a french search engine.

This class exports no public interface; all interaction should be done through WWW::Search objects.

Search::VectorSpace is a very basic vector-space search engine.

SYNOPSIS

use Search::VectorSpace;

my @docs = ...;
my $engine = Search::VectorSpace->new( docs => @docs, threshold => .04);
$engine->build_index();

while ( my $query = ) {
my %results = $engine->search( $query );
print join "n", keys %results;
}

This module takes a list of documents (in English) and builds a simple in-memory search engine using a vector space model. Documents are stored as PDL objects, and after the initial indexing phase, the search should be very fast. This implementation applies a rudimentary stop list to filter out very common words, and uses a cosine measure to calculate document similarity. All documents above a user-configurable similarity threshold are returned.
