Criterion independence

Example of Criterions not relating to each other:

There is a Content with two Locations: Location A and Location B

- Location A is visible
- Location B is hidden

Searching with LocationId criterion with Location B id and Visibility
criterion with Visibility::VISIBLE will return the Content because
conditions are satisfied:

- Content has Location B
- Content is visible (it has Location A that is visible)

Code:

<?php

use eZ\Publish\API\Repository\Values\Content\Query;
use eZ\Publish\API\Repository\Values\Content\Query\Criterion\LogicalAnd;
use eZ\Publish\API\Repository\Values\Content\Query\Criterion\LocationId;
use eZ\Publish\API\Repository\Values\Content\Query\Criterion\Visibility;

/** @var string|int $locationBId */
/** @var \eZ\Publish\API\Repository\Repository $repository */

$searchService = $repository->getSearchService();

$query = new Query(
    array(
        'filter' => new LogicalAnd(
            array(
                new LocationId( $locationBId ),
                new Visibility( Visibility::VISIBLE ),
            )
        )
    )
);

$searchResult = $searchService->findContent( $query );

// Content is found
$content = $searchResult->searchHits[0];
