Query represents a SELECT SQL statement.

Query provides a set of methods to facilitate the specification of different clauses in a SELECT statement. These methods can be chained together.

By calling createCommand(), we can get a yii\sphinx\Command instance which can be further used to perform/execute the Sphinx query.

For example,

$query = new Query();
$query->select('id, group_id')
    ->from('idx_item')
    ->limit(10);
// build and execute the query
$command = $query->createCommand();
// $command->sql returns the actual SQL
$rows = $command->queryAll();

Since Sphinx does not store the original indexed text, the snippets for the rows in query result should be build separately via another query. You can simplify this workflow using snippetCallback().

Warning: even if you do not set any query limit, implicit LIMIT 0,20 is present by default!

Property Details

$connection public property

Sphinx connection instance

public yii\sphinx\Connection getConnection ( )
public $this setConnection ( $connection )

$facets public property

Facet search specifications. For example:

[
    'group_id',
    'brand_id' => [
        'order' => ['COUNT(*)' => SORT_ASC],
    ],
    'price' => [
        'select' => 'INTERVAL(price,200,400,600,800) AS price',
        'order' => ['FACET()' => SORT_ASC],
    ],
    'name_in_json' => [
        'select' => [new Expression('json_attr.name AS name_in_json')],
    ],
]

You need to use search() method in order to fetch facet results.

Note: if you specify custom select for the facet, ensure facet name has corresponding column inside it.

public array $facets = []

$groupLimit public property (available since version 2.0.6)

Groups limit: to return (no more than) N top matches for each group. This option will take effect only if groupBy() is set.

public integer $groupLimit = null

$match public property

Text, which should be searched in fulltext mode. This value will be composed into MATCH operator inside the WHERE clause. Note: this value will be processed by yii\sphinx\Connection::escapeMatchValue(), if you need to compose complex match condition use yii\db\Expression, see match() for details.

public string|yii\db\Expression $match = null

$options public property

Per-query options in format: optionName => optionValue They will compose OPTION clause. This is a Sphinx specific extension that lets you control a number of per-query options.

public array $options = null

$showMeta public property

Whether to automatically perform 'SHOW META' query against main one. You may set this value to be string or yii\db\Expression instance, in this case its value will be used as 'LIKE' condition for 'SHOW META' statement. You need to use search() method in order to fetch 'meta' results.

public boolean|string|yii\db\Expression $showMeta = null

$snippetCallback public property

PHP callback, which should be used to fetch source data for the snippets. Such callback will receive array of query result rows as an argument and must return the array of snippet source strings in the order, which match one of incoming rows. For example:

$query = new Query();
$query->from('idx_item')
    ->match('pencil')
    ->snippetCallback(function ($rows) {
        $result = [];
        foreach ($rows as $row) {
            $result[] = file_get_contents('/path/to/index/files/' . $row['id'] . '.txt');
        }
        return $result;
    })
    ->all();

public callable $snippetCallback = null

$snippetOptions public property

Query options for the call snippet.

public array $snippetOptions = null

$tablesUsedInFrom public read-only property

Table names indexed by aliases

public string[] getTablesUsedInFrom ( )

$within public property

WITHIN GROUP ORDER BY clause. This is a Sphinx specific extension that lets you control how the best row within a group will to be selected. The possible value matches the orderBy() one.

public string $within = null

innerJoin() public method

Appends an INNER JOIN part to the query.

public $this innerJoin ( $table, $on = '', $params = [] )
$table	string\|array	The table to be joined. Use a string to represent the name of the table to be joined. The table name can contain a schema prefix (e.g. 'public.user') and/or table alias (e.g. 'user u'). The method will automatically quote the table name unless it contains some parenthesis (which means the table is given as a sub-query or DB expression). Use an array to represent joining with a sub-query. The array must contain only one element. The value must be a yii\sphinx\Query object representing the sub-query while the corresponding key represents the alias for the sub-query.

$on	string\|array	The join condition that should appear in the ON part. Please refer to where() on how to specify this parameter. Note that the array format of where() is designed to match columns to values instead of columns to columns, so the following would not work as expected: `['post.author_id' => 'user.id']`, it would match the `post.author_id` column value against the string `'user.id'`. It is recommended to use the string syntax here which is more suited for a join: `'post.author_id = user.id'`
$params	array	The parameters (name => value) to be bound to the query.
return	$this	The query object itself

leftJoin() public method

Appends a LEFT OUTER JOIN part to the query.

$query->from('my_index')
    ->match(new Expression(':match', ['match' => '@(content) ' . Yii::$app->sphinx->escapeMatchValue($matchValue)]))
    ->all();
