NAME

ElasticSearch::ScrolledSearch - Description

SYNOPSIS

    $scroller = $es->scrolled_search($search_params);
  OR
    $scroller = ElasticSearch::ScrolledSearch($es,$search_params);

    while (my $result = $scroller->next) {
        # do something
    }

    $total = $scroller->total;
    $bool  = $scroller->eof
    $score = $scroller->max_score;

DESCRIPTION

ElasticSearch::ScrolledSearch is a convenience iterator for scrolled searches. It accepts the standard search parameters that would be passed to "search()" in ElasticSearch and requires a scroll parameter, eg:

    $scroller = $es->scrolled_search(
                    query  => {match_all=>{}},
                    scroll => '5m'               # keep the scroll request
                                                 # live for 5 minutes
                );

METHODS

new()

    $scroller = $es->scrolled_search($search_params);
  OR
    $scroller = ElasticSearch::ScrolledSearch($es,$search_params);

next()

    @results = $scroller->next()
    @results = $scroller->next($no_of_results);

Returns the next result, or the next $no_of_results or an empty list when no more results are available.

An error is thrown if the scroll has already expired.

total()

    $total = $scroller->total

The total number of hits

max_score()

    $score = $scroller->max_score

The max_score returned from the first search request (if available).

eof()

    $bool = $scroller->eof

Returns true if no more results are available. Note: if no results match the search, then eof() could be false but the first call to next() will return zero results.
