WebService::CIA::Source::DBM - An interface to a DBM copy of the CIA World Factbook SYNOPSIS
use WebService::CIA::Source::DBM; my $source = WebService::CIA::Source::DBM->new({ DBM => 'factbook.dbm', Mode => 'read' }); DESCRIPTION
WebService::CIA::Source::DBM is an interface to a pre-compiled DBM copy of the CIA World Factbook. The module can also be used to make the DBM file, taking data from WebService::CIA::Parser (or WebService::CIA::Source::Web) and inserting it into a DBM. A script to do this - webservice-cia-makedbm.pl - should be included in this module's distribution. METHODS
Apart from "new", these methods are normally accessed via a WebService::CIA object. "new(\%opts)" This method creates a new WebService::CIA::Source::DBM object. It takes a hashref of options. Valid keys are "DBM" and "Mode". DBM is mandatory and should be the location of the DBM file to be used. Mode is optional and can be either "read" or "readwrite". It defaults to "read". "value($country_code, $field)" Retrieve a value from the DBM. $country_code should be the FIPS 10-4 country code as defined in <https://www.cia.gov/library/publications/the-world-factbook/appen- dix/appendix-d.html>. $field should be the name of the field whose value you want to retrieve, as defined in <https://www.cia.gov/library/publica- tions/the-world-factbook/docs/notesanddefs.html>. (WebService::CIA::Parser also creates four extra fields: "URL", "URL - Print", "URL - Flag", and "URL - Map" which are the URLs of the country's Factbook page, the printable version of that page, a GIF map of the coun- try, and a GIF flag of the country respectively.) "all($country_code)" Returns a hashref of field-value pairs for $country_code or an empty hashref if $country_code isn't in the DBM. "set($country_code, $data)" Insert or update data in the DBM. $country_code should be as described above. $data is a hashref of the data to store (as Field => Value). "set" overwrites any data already in the DBM under $country_code. "dbm()" Returns a reference to the DBM file in use. AUTHOR

WebService::Solr::Query(3pm) User Contributed Perl Documentation WebService::Solr::Query(3pm) NAME
WebService::Solr::Query - Abstract query syntax for Solr queries SYNOPSIS
my $query = WebService::Solr::Query->new( { foo => 'bar' } ); my $result = $solr->search( $query ); DESCRIPTION
WebService::Solr::Query provides a programmatic way to generate queries to be sent to Solr. Syntax wise, it attempts to be as close to SQL::Abstract WHERE clauses as possible, with obvious exceptions for idioms that do not exist in SQL. Just as values in SQL::Abstract are SQL-escaped, this module does the appropriate Solr-escaping on all values passed to the object (see "escape()"). QUERY SYNTAX
Key-Value Pairs The simplest way to search is with key value pairs. my $q = WebService::Solr::Query->new( { foo => 'bar' } ); # RESULT: (foo:"bar") Implicit AND and OR By default, data received as a HASHREF is AND'ed together. my $q = WebService::Solr::Query->new( { foo => 'bar', baz => 'quux' } ); # RESULT: (foo:"bar" AND baz:"quux") Furthermore, data received as an ARRAYREF is OR'ed together. my $q = WebService::Solr::Query->new( { foo => [ 'bar', 'baz' ] } ); # RESULT: (foo:"bar" OR foo:"baz") Nested AND and OR The ability to nest AND and OR boolean operators is essential to express complex queries. The "-and" and "-or" prefixes have been provided for this need. my $q = WebService::Solr::Query->new( { foo => [ -and => { -prohibit => 'bar' }, { -require => 'baz' } ] } ); # RESULT: (((-foo:"bar") AND (+foo:"baz"))) my $q = WebService::Solr::Query->new( { foo => [ -or => { -require => 'bar' }, { -prohibit => 'baz' } ] } ); # RESULT: (((+foo:"bar") OR (-foo:"baz"))) Default Field To search the default field, use the "-default" prefix. my $q = WebService::Solr::Query->new( { -default => 'bar' } ); # RESULT: ("bar") Require/Prohibit my $q = WebService::Solr::Query->new( { foo => { -require => 'bar' } } ); # RESULT: (+foo:"bar") my $q = WebService::Solr::Query->new( { foo => { -prohibit => 'bar' } } ); # RESULT: (-foo:"bar") Range There are two types of range queries, inclusive ("-range_inc") and exclusive ("-range_exc"). The "-range" prefix can be used in place of "-range_inc". my $q = WebService::Solr::Query->new( { foo => { -range => ['a', 'z'] } } ); # RESULT: (+foo:[a TO z]) my $q = WebService::Solr::Query->new( { foo => { -range_exc => ['a', 'z'] } } ); # RESULT: (+foo:{a TO z}) Boost my $q = WebService::Solr::Query->new( { foo => { -boost => [ 'bar', '2.0' ] } } ); # RESULT: (foo:"bar"^2.0) Proximity my $q = WebService::Solr::Query->new( { foo => { -proximity => [ 'bar baz', 10 ] } } ); # RESULT: (foo:"bar baz"~10) Fuzzy my $q = WebService::Solr::Query->new( { foo => { -fuzzy => [ 'bar', '0.8' ] } } ); # RESULT: (foo:bar~0.8) Boost my $q = WebService::Solr::Query->new( { foo => { -boost => [ 'bar', '2.0' ] } } ); # RESULT: (foo:"bar"^2.0) Literal Queries Specifying a scalar ref as a value in a key-value pair will allow arbitrary queries to be sent across the line. NB: This will bypass any data massaging done on regular strings, thus the onus of properly escaping the data is left to the user. my $q = WebService::Solr::Query->new( { '*' => '*' } ) # RESULT (*:*) ACCESSORS
o query - stores the original query structure METHODS
new( \%query ) Creates a new query object with the given hashref. stringify( ) Converts the supplied structure into a Solr/Lucene query. escape( $value ) The following values must be escaped in a search value: + - & | ! ( ) { } [ ] ^ " ~ * ? : NB: Values sent to "new()" are automatically escaped for you. unescape( $value ) Unescapes values escaped in "escape()". D Debugging constant, default: off. BUILDARGS Moose method to handle input to "new()". SEE ALSO
