Query Text Parser
The Query Text Parser library performs search query text parsing.
This allows you to write a search query in free form text and parse it into a machine-readable parsing tree.
The library is fully unit-tested.
Features
- AND/OR operators
- Grouped queries using paranthesis -- i.e.
(Denver AND Boston) OR Miami
- Multi-word search queries using quotes -- i.e.
"San Francisco" AND Chicago
Example usage
$parser = new Engage\QueryTextParser\Parser; $result = $parser->parse('(Chicago AND Houston) OR Phoenix'); print_r($result);
Output
Engage\QueryTextParser\Data\Group Object
(
[type] => OR
[children] => Array
(
[0] => Engage\QueryTextParser\Data\Group Object
(
[type] => AND
[children] => Array
(
[0] => Engage\QueryTextParser\Data\Partial Object
(
[text] => Chicago
[negate] =>
)
[1] => Engage\QueryTextParser\Data\Partial Object
(
[text] => Houston
[negate] =>
)
)
)
[1] => Engage\QueryTextParser\Data\Partial Object
(
[text] => Phoenix
[negate] =>
)
)
)
TODO
- Support negating operator (i.e. NOT)
