Searching

A search is a SearchRequest for an index (or alias) with a SearchSourceBuilder body.

<?php
use Zvonchuk\Elastic\Core\SearchRequest;
use Zvonchuk\Elastic\Query\QueryBuilders;
use Zvonchuk\Elastic\Search\Builder\SearchSourceBuilder;

$source = (new SearchSourceBuilder())
    ->query(QueryBuilders::matchQuery('title', 'php'))
    ->from(0)
    ->size(20)
    ->include(['id', 'title']);

$response = $client->search((new SearchRequest('articles'))->source($source));

Responses — typed hits, matched queries, mapping hits to your own classes
Multi search — several searches in one round trip

Search options

Method	Elasticsearch	Purpose
`query()`	`query`	the query
`from()`, `size()`	`from`, `size`	paging (defaults 0 and 10)
`include()`, `exclude()`	`_source`	which source fields to return
`sort()`	`sort`	see Sorting
`aggregation()`	`aggregations`	see Aggregations
`searchAfter()`	`search_after`	deep paging after the last hit’s sort values
`timeout('2s')`	`timeout`	per-shard time limit; partial results come back with `timedOut() === true`
`trackTotalHits(false)`	`track_total_hits`	skip counting all hits (faster); `getTotal()` is then `null`. An int counts up to that number
`minScore(3.5)`	`min_score`	leave out weak hits
`explain()`	`explain`	score explanation per hit (`SearchHit::$explanation`); slow, for debugging

A SearchRequest without a source searches with the defaults; a CountRequest without a query counts everything.
