NAME

Catmandu::Searchable - Optional role for searchable stores

SYNOPSIS

    my $store = Catmandu::Store::Solr->new();
    # Return one page of search results (page size = 1000)
    my $hits  = $store->bag->search(
           query => 'dna' ,
           start => 0 ,
           limit => 100 ,
           sort  => 'title desc',
                );
    # Return all the search results as iterator
    my $it    = $store->bag->searcher(query => 'dna');
    $it->each(sub { ...});
    $store->bag->delete_by_query(query => 'dna');

CONFIGURATION

default_limit

The default value for "limit". By default this is 10.

maximum_limit

The maximum allowed value for "limit". By default this is 1000.

maximum_offset

The maximum allowed offset. When set no hits will be returned after hit offset is greater than "maximum_offset", this to avoid deep paging problems. Pagination values will be also be adjusted accordingly.

METHODS

search(query => $query, start => $start, page => $page, limit => $num, sort => $sort)

Search the database and returns a Catmandu::Hits on success. The Hits represents one result page of at most $num results. The $query and $sort should implement the query and sort syntax of the underlying search engine. Optionally provide the index of the first result using the "start" option, or the starting page using the "page" option. The number of records in a result page can be set using the "limit" option. Sorting options are being sent verbatim to the underlying search engine.

searcher(query => $query, start => $start, limit => $num, sort => $sort, cql_query => $cql)

Search the database and return a Catmandu::Iterable on success. This iterator can be used to loop over the complete result set. The $query and $sort should implement the query and sort syntax of the underlying search engine. Optionally provide the index of the first result using the "start" option. The number of records in a page can be set using the "limit" option. Sorting options are being sent verbatim to the underlying search engine.

delete_by_query(query => $query)

Delete items from the database that match $query

CQL support

Stores that are support the CQL query language <https://www.loc.gov/standards/sru/cql/> also accept the "cql_query" and "sru_sortkeys" arguments. See Catmandu::CQLSearchable for more information.
