NAME

    Interchange::Search::Solr -- Solr query encapsulation

VERSION

    Version 0.10

DESCRIPTION

    Exposes Solr search API in a programmer-friendly way.

SYNOPSIS

    Quick summary of what the module does.

    Perhaps a little code snippet.

        use Interchange::Search::Solr;
        my $solr = Interchange::Search::Solr->new(solr_url => $url);
        $solr->rows(10);
        $solr->start(0);
        $solr->search('shirts');
        $results = $solr->results;

ACCESSORS

 solr_url

    Url of the solr instance. Read-only.

 input_encoding [DEPRECATED]

    Assume the urls to be in this encoding, so decode it before parsing it.
    This is basically a (probably bugged) workaround when you have all the
    shop in latin1. If the search keep crashing on non-ascii characters,
    try to set this to iso-8859-1.

 rows

    Number of results to return. Read-write (so you can reuse the object).

 page_scope

    The number of paging items for the paginator

 search_fields

    An arrayref with the indexed fields to search. Defaults to:

      [qw/sku name description/]

    You can add boost to fields appending a float with a caret.

      [qw/ sku^5.0 name^1.0 description^0.4 /]

 return_fields

    An arrayref of indexed fields to return. All by default.

 facets

    A string or an arrayref with the fields which will generate a facet.
    Defaults to

     [qw/suchbegriffe manufacturer/]

 start

    Start of pagination. Read-write.

 page

    Current page. Read-write.

 filters

    An hashref with the filters. E.g.

     {
      suchbegriffe => [qw/xxxxx yyyy/],
      manufacturer => [qw/pikeur/],
     }

    The keys of the hashref, to have any effect, must be one of the facets.

 response

    Read-only accessor to the response object of the current search.

 facets_found

    After a search, the structure with the facets can be retrieved with
    this accessor, with this structure:

     {
       field => [ { name => "name", count => 11 }, { name => "name", count => 9 }, ...  ],
       field2 => [ { name => "name", count => 7 }, { name => "name", count => 6 }, ...  ],
       ...
     }

    Each hashref in each field's arrayref has the following keys:

    name

      The name to display

    count

      The count of item

    query_url

      The url fragment to toggle this filter.

    active

      True if currently in use (to be used for, e.g., checkboxes)

 search_string

    Debug only. The search string produced by the query.

 search_terms

    The terms used for the current search.

 search_structure

    The perl data structure used for the current search. It's passed to
    Webservice::Solr::Query for stringification.

 sorting

    The field used to sort the result (optional and defaults to score, as
    per Solr doc).

 sorting_direction

    The direction used by the sorting, when sorting is specified. Default
    to 'desc'.

 wild_matching

    By default, a search term produce a query with a wildcard appended. So
    searching for 1234 will query 1234*. With this option set to true, a
    wildcard is prepended as well, querying for *1234* instead).

 stop_words_langs

    The languages for which we should build the stop word list. It defaults
    to:

     [ 'en' ]

    New in 0.10. To revert to the old behaviour (no filtering of
    stopwords), pass an empty arrayref.

 min_chars

    Minimum characters for filtering the search terms. Default to 3.

    New in 0.10. To revert to the old behaviour, set it to 0.

 permit_empty_search

    By default, empty searches are not executed. You can permit them
    setting this accessor to 1. The module will reset it to 0 when the
    search is executed.

INTERNAL ACCESSORS

 solr_object

    The WebService::Solr instance.

METHODS

 search( [ $string_or$structure ] ])

    Run a search and return a WebService::Solr::Response object.

    The method accept zero or one argument.

    With no arguments, run a full wildcard search.

    With one argument, if it's a string, run the search against all the
    indexed fields. If it's a structure, build a query for it. The syntax
    of the structure is described at WebService::Solr::Query.

    After calling this method you can inspect the response using the
    following methods:

 results

    Returns reference to list of results, each result is a hash reference.

 skus_found

    Returns just a plain list of skus.

 num_found

    Return the number of items found

 has_more

    Return true if there are more pages

 execute_query($query)

    Accept either a raw string with the query or a WebService::Solr::Query
    object and run the query against the Solr service.

    If no query is provided, a wildcard search is performed.

 construct_params

    Constructs parameters for the search.

 maintainer_update($mode)

    Perform a maintainer update and return a WebService::Solr::Response
    object.

 reset_object

    Reset the leftovers of a possible previous search.

 search_from_url($url)

    Parse the url provided and do the search.

 add_terms_to_url($url, $string)

    Parse the url, and return a new one with the additional words added.
    The page is discarded, while the filters are retained.

 current_search_to_url

    Return the url for the current search.

 url_builder(\@terms, \%filters, $page);

    Build a query url with the parameter passed

 paginator

    Return an hashref suitable to be turned into a paginator, undef if
    there is no need for a paginator.

    Be careful that a defined empty string in the first/last/next/previous
    keys is perfectly legit and points to an unfiltered search which will
    return all the items, so concatenating it to the prefix is perfectly
    fine (e.g. "products/" . ''). When rendering this structure to HTML,
    just check if the value is defined, not if it's true.

    The structure looks like this:

     {
       first => 'words/bla' || undef,
       first_page => 1 || undef,
       last  => 'words/bla/page/5' || undef,
       last_page => 5 || undef,
       next => 'words/bla/page/5' || undef,
       next_page => 5 || undef
       previous => 'words/bla/page/3' || undef,
       previous_page => 3 || undef,
       pages => [
                 {
                  name => 1,
                  url => 'words/bla/page/1',
                 },
                 {
                  name => 2,
                  url => 'words/bla/page/2',
                 },
                 {
                  name => 3,
                  url => 'words/bla/page/3',
                 },
                 {
                  name => 4,
                  url => 'words/bla/page/4',
                  current => 1,
                 },
                 {
                  name => 5,
                  url => 'words/bla/page/5',
                 },
                ]
       total_pages => 5
     }

 terms_found

    Returns an hashref suitable to build a widget with the terms used and
    the links to toggle them. Return undef if no terms were used in the
    search.

    The structure looks like this:

     {
      reset => '',
      terms => [
                { term => 'first', url => 'words/second' },
                { term => 'second', url => 'words/first' },
               ],
     }

    See also:

    clear_words_link

      Which return the reset link

    remove_word_links

      Which returns a list of hashrefs with uri and label for each word to
      remove.

 version

    Return the version of this module.

 breadcrumbs

    Return a list of hashrefs with uri and label suitable to compose a
    breadcrumb for the current search.

    If the breadcrumb points to a facet, the facet name is stored in the
    facet key.
