Return documents that contain text as parameter

Can anyone help how do I return documents that contain the supplied text as a parameter?
This text should be researched in the fields: “nome”, “fone” (array), “razao”, “produto”, “logradouro”, “titulos” (array) and “titular” (array).

This query is similar to LIKE ‘%text%’ SQL, the text may be the beginning, middle or end.
Please can someone help?
Below is the structure of my documents.
Need to do this in Couchbase Lite.

Couchbase Lite on iOS has full-text query capability. It’s not available on the other platforms yet. (You haven’t said what platform you’re developing for.)

Thanks for the feedback!
I’m developing for Android.
I am using Xamarin Studio and Android Xamarin with C #.
Is it possible?
