Informations about the package sphinx
SphinxServiceProvider
This is a simple service provider for silex that ties the SphinxSearch-API in.
A word of warning
This is currently work in progress and not suitable for use in productive environments.
The API may change often and erratically. Generally, I would advise against using this before version 1.0.0
I you'd really like to use this productively, I recommend to choose a version and stick with it, i.e. set "require 'ttf/sphinx': '0.1.2'" in your composer.json
Usage
Register the service provider as you would any other:
$app->register( new Ttf\SphinxServiceProvider());
If you're running the sphinx searchd on any host/port combination other than the assumed "localhost:3312", you need to supply these parameters here:
$app->register( new Ttf\SphinxServiceProvider(), array(
'sphinx.port' => 3413,
'sphinx.host' => 'sphinx.example.org'
));
Following that, you would use it as any other service provider. Start off by using the search method on the provider, which will return a result object:
$app->get('/search', function( Request $request ) use ($app) {
$result = $app['sphinx']->search( $request->get('q'), 'myCatalog' );
return new Response( (String) $result, 200 );
});
Coercing the $result object to a string will return a human readable representation of your research results.
In this case, a call request would look like:
http://silex.local/search?q=cheese
A more elaborate example would be:
$app->get('/search', function( Request $request ) use ($app) {
if( $result = $app['sphinx']->search( $request->get('q'), 'catalog' ) ) {
$indices = $result->fetchIndices();
$query = 'Select description, tags from stand where fiorg = ?';
foreach( $indices as $index ) {
$entries = $app['db']->fetchAssoc( $query, array( $index ));
}
$app['twig']->render('search.twig',
array(
'results' => $entries
)
);
}
});
Passing parameters to the Sphinx API
Note that you can also directly pass arguments to the sphinxsearch api. Simply use them on the service:
$app['sphinx']->SetRankingMode( SPH_RANK_SPH04 );
$app['sphinx']->SetFieldWeights( array( 'tags' => 10, 'description' => 5) );
