How to configure correctly FOS Elastica analyzers and filters? - symfony

Question

In my symfony2 application, I am using FOS Elastica bundle to perform searches.
I have tried to set up analyzers and filters but it seems they just have no effect. For instance, if I search for the word 'cake', the objects containing the sentence case 'Cake' won't be returned.
How can I configure those analyzers and filters correctly ?
My config :
#Elastic Search

The query is a basic one :
$finder = $this->container->get('website.recipe')
$elasticaResults = $finder->find($search);

Each time you update your fos_elastica config file, you need in a first time to update the index(es) with the command:
php app/console fos:elastica:populate --index website --type= <<you type>>
This command will reindex your data with erasing previous one. In a second time, you should have to check your mapping information to check everything is fine and synchronous.
You could check your analyser with this command:
curl 'http://<< yourdomain >>:9200/website/_analyze?pretty=true&analyzer=custom_french_analyzer' -d "Cake"
