ElasticSearch::ScrolledSearch - Description
$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;
ElasticSearch::ScrolledSearch is a convenience iterator for scrolled searches. It accepts the standard search parameters that would be passed to "search()" in ElasticSearch. The scroll parameter defaults to 1m.
ElasticSearch::ScrolledSearch
scroll
1m
$scroller = $es->scrolled_search( query => {match_all=>{}}, scroll => '5m' # keep the scroll request # live for 5 minutes );
new()
$scroller = $es->scrolled_search($search_params); OR $scroller = ElasticSearch::ScrolledSearch($es,$search_params);
@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.
$no_of_results
An error is thrown if the scroll has already expired.
$total = $scroller->total
The total number of hits
$score = $scroller->max_score
The max_score returned from the first search request (if available).
max_score
$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.
true
eof()
false
next()
"scrolled_search()" in ElasticSearch, "search()" in ElasticSearch and "scroll()" in ElasticSearch
