You should look at the `_analyze` API. It will basically help you to understand how your text is processed before getting indexed.

I don't think so.  
If you need help on that, please share what you are exactly doing. I mean a simple example with the real mapping and real document and query would help.

A full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) would help. Please, try to keep the example as simple as possible.
