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.

Search::Glimpse is a Perl extension to communicate with Glimpse server.

SYNOPSIS

use Search::Glimpse;

ABSTRACT

This module is an extension to use glimpse server from Perl.

Quick hack to connect to glimpse server.

new

Creates a new glimpse object.

search

Search on a glimpse object

hits

Returns the number of hits...

files

Search::FreeText is a free text indexing module for medium-to-large text corpuses.

SYNOPSIS

my $test = new Search::FreeText(-db => [DB_File, "stories.db"]);

$text->open_index();
$text->clear_index();
$text->index_document(1, "Hello world");
$text->index_document(2, "World in motion");
$text->index_document(3, "Cruel crazy beautiful world");
$text->index_document(4, "Hey crazy");
$text->close_index();

$text->open_index();
foreach ($text->search("Crazy", 10)) {
print "$_->[0], $_->[1]n";
};
$text->close_index();

This module provides free text searching in a relatively open manner. It allows a persistent inverted file index to be constructed and managed (within limits), and then to be searched fairly efficiently. The module depends on a DBM module of some kind to manage the inverted file (DB_File is usually the best choice, as it is quite fast, quite scaleable, and accepts the long values that are needed for performance.

The free text searching algorithm used is the BM25 weighting scheme described in Robertson, S. E., Walker, S., Beaulieu, M. M., Gatford, M., and Payne, A. (1995). Okapi at TREC-4, in NIST Special Publication 500-236, the Fourth Text Retrieval Conference (TREC-4), pages 73-96.

Much of the module depends on an open lexical analysis system, which is implemented by Search::FreeText::LexicalAnalysis. This is where all the word splitting and stemming is handled (Lingua::Stem is used for the stemming).

Using the module is quite simple: you can open an index and close it, and while it is open you add documents as strings, each with a key of your own choosing. You can search the corpus using a string, and you get back a list of matches, each an array of your own document key and a relevance measure. So, for example, the keys might be database table keys, URLs, file names, anything like that will do. This makes Search::FreeText a very useful package to implement fairly efficient and high quality search systems.

WWW::Search::GoTo is Perl class for searching GoTo.com.

SYNOPSIS

require WWW::Search;
$search = new WWW::Search(GoTo);

This class is an GoTo specialization of WWW::Search. It handles making and interpreting GoTo searches www-GoTo.com.

Nothing special about GoTo: no search options. It is much like Google in that it attempts to returm relavent search results using simple queries.

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

WWW::Search::Scraper::YahooFinance is a Perl module that scrapes Finance.Yahoo.com

SYNOPSIS

require WWW::Search::Scraper;
$search = new WWW::Search::Scraper(YahooFinance);

($dow, $nasdaq, $sap, $tenYrBond, $nyseVolume, $nasdaqVolume)
= $scraper->getMarketSummary();

This class is an YahooFinance extension of WWW::Search::Scraper. It handles making and interpreting Yahoo Finance searches http://Finance.Yahoo.com.
The Search capabilities of module are not yet implemented; only the getMarketSummary method is implemented.

OPTIONS

getMarketSummary

Gets the "Market Summary" data off of finance.yahoo.com.

$scraper = new WWW::Search::Scraper(YahooFinance);
($dow, $nasdaq, $sap, $tenYrBond, $nyseVolume, $nasdaqVolume)
= $scraper->getMarketSummary();

WWW::Search::Scraper::NorthernLight it scrapes NorthernLight.com.

SYNOPSIS

require WWW::Search::Scraper;
$search = new WWW::Search::Scraper(NorthernLight);

This class is an NorthernLight specialization of WWW::Search. It handles making and interpreting NorthernLight searches http://www.NorthernLight.com.

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

Search::QueryParser parses a query string into a data structure suitable for external search engines.

SYNOPSIS

my $qp = new Search::QueryParser;
my $s = +mandatoryWord -excludedWord +field:word "exact phrase";
my $query = $qp->parse($s) or die "Error in query : " . $qp->err;
$someIndexer->search($query);

# query with comparison operators and implicit plus (second arg is true)
$query = $qp->parse("txt~^foo.* date>=01.01.2001 date<<less
