Hi.
This is my text index:

db.test.createIndex({ 'description' : 'text' }, { default_language : 'spanish' })

This is my document:

db.test.find({ _id : 1 })
{ "_id" : 1, "description" : "Obtención de financiación" }

These are my questions:

db.test.find({ $text : { $search : 'Obtencion' } });
{ "_id" : 1, "description" : "Obtención de financiación" }
> db.test.find({ $text : { $search : 'financiacion' } });
>

Why I do not receive the same document as a result of my last command?
Why "diacriticSensitive : false" does not work when the searched word (financiacion) is not located at the very beginning of the field?
Is this a issue or I do not understand something?
¡Thank you very much!
