Parses Lucene/Google style search strings into PostgresSQL full text query string.

Installation

composer require digitlab/search-parser

Add the service provider in app/config/app.php:

Usage

Basic Usage

To just parse a full text query you can simply use SearchParser:

$parser = new SearchParser();
$filters = $parser->parse('string to parse');

will produce

[
    'search' => 'string&to&parse'
]

Filters

To handle filters you need to extend SearchParser and add a handle function or add a pass through filter:

class CustomSearchParser extends SearchParser
{
    /**
     * The filters that should be returned without handlers.
     *
     * @var array
     */
    protected $passthruFilters = ['other'];

    /**
     * Handle the state filter.
     *
     * @param mixed $state
     * @return array
     */
    protected function handleState($state)
    {
        return ['some' => $state];
    }
}

$parser = new CustomSearchParser();
$filters = $parser->parse('state:pending other:string string to parse');

will produce

[
    'search' => 'string&to&parse',
    'some' => 'pending',
    'other' => 'string'
]

Custom Query Key

You can customise the array key of the query by overriding the $queryName variable in your custom class.

class CustomSearchParser extends SearchParser
{
    /**
     * The name of the query in the result array.
     *
     * @var string
     */
    protected $queryName = 'other';
}

$parser = new CustomSearchParser();
$filters = $parser->parse('string to parse');

will produce

[
    'other' => 'string&to&parse'
]
