NAME
URI::ParseSearchString::More - Extract search strings from more
referrers.
VERSION
version 0.17
SYNOPSIS
use URI::ParseSearchString::More;
my $more = URI::ParseSearchString::More;
my $search_terms = $more->se_term( $search_engine_referring_url );
DESCRIPTION
This module is a subclass of URI::ParseSearchString, so you can call any
methods on this object that you would call on a URI::ParseSearchString
object. This module works a little harder than its SuperClass to get you
results. If it fails, it will return to you the results that
URI::ParseSearchString would have returned to you anyway, so it should
function well as a drop-in replacement.
WWW::Mechanize is used to extract search strings from some URLs which
contain session info rather than search params. Optionally,
WWW::Mechanize::Cached can be used to cache your lookups. There is
additional parsing and also a guess() method which will return good
results in many cases of doubt.

USAGE
use URI::ParseSearchString::More;
my $more = URI::ParseSearchString::More->new;
my $search_terms = $more->se_term( $url );
URI::ParseSearchString
parse_search_string( $url )
At this point, this is the only "extended" URI::ParseSearchString
method. This method performs the following bit of logic:
1) If the URL supplied looks to be a search query with session info
rather than search data in the URL, it will attempt to access the URL
and extract the search terms from the page returned.
2) If this returns no results, the URL will be processed by parse_more()
3) If there are still no results, the results of
URI::ParseSearchString::se_term will be returned.
WWW::Mechanize::Cached can be used to speed up your movement through
large log files which may contain multiple similar URLs:
use URI::ParseSearchString::More;
my $more = URI::ParseSearchString::More->new;
$more->set_cached( 1 );
my $search_terms = $more->se_term( $url );
One interesting thing to note is that maps.google.* URLs have 2
important params: "q" and "near". The same can be said for
local.google.* I would think the results would be incomplete without
including the value of "near" in the search terms for these searches.
So, expect the following results:
my $url = ""http://local.google.ca/local?sc=1&hl=en&near=Stratford%20ON&btnG=Google%20Search&q=home%20health";
my $terms = $more->parse_search_string( $url );
# $terms will = "home health Stratford ON"
Engines with session info currently supported:
aol.com
se_term( $url )
A convenience method which calls parse_search_string.
URI::ParseSearchString::More
blame
Returns the name of the module that came up with the results on the last
string parsed by parse_search_string(). Possible results:
URI::ParseSearchString
URI::ParseSearchString::More
set_cached( 0|1 )
Turn caching off and on. As of version 0.08 caching is OFF by default.
See KNOWN ISSUES below for more info on this.
get_cached
Returns 1 if caching is currently on, 0 if it is not.
get_mech
This gives you direct access to the Mechanize object. If caching is
enabled, a WWW::Mechanize::Cached object will be returned. If caching is
disabled, a WWW::Mechanize object will be returned.
If you know what you're doing, play around with it. Caveat emptor.
use URI::ParseSearchString::More;
my $more = URI::ParseSearchString::More;
my $mech = $more->get_mech();
$mech->agent("My Agent Name");
my $search_terms = $more->se_term( $search_engine_referring_url );
parse_more( $url )
Handles the bulk of More's parsing. This is automatically called (if
needed) when you pass a search string to se_term(). However, you may
also call it directly. Just keep in mind that this method will NOT try
to get results from URI::ParseSearchString if it comes up empty.
guess( $url )
For the most part, the parsing that goes on is done with specific search
engines (ie. the ones that we already know about) in mind. However, in a
lot cases, a good guess is all that you need. For example, a URI which
contains a query string with the parameter "q" or "query" is generally
the product of a search. If se_term() or parse_more() has come up empty,
guess may just provide you with a valid search term. Then again, it may
not. Caveat emptor.
TO DO
I've pretty much added all of the search engines I care about. If you'd
like something added, please get in touch.
NOTES
Despite its low version number, this module is now stable.
KNOWN ISSUES
As of 0.13 WWW::Mechanize::Cached 1.33 is required. This solves the
errors which were being thrown by Storable.
