Title: Introduction

Describe the issue:
paragraph "Red Hat JBoss Data Grid's version of Hibernate Search is slightly modified and named Infinispan Query. Much of the information in this guide is relevant to Hibernate Search as well as Infinispan Query. However, for a comprehensive Hibernate Search only document, see the JBoss Web Framework Kit Hibernate Search document. "


Suggestions for improvement:
it's not actually "slightly modified" as it's the same library (no modifications).
I would clarify that Hibernate Search's functionality is included, and we call "Infinispan Query" the combination of the Query capabilities of Hibernate Search with the core of Infinispan.
Therefore many APIs and concepts are similar, and the annotations used to map objects to indexes use the same package domain _org.hibernate.search._.

There's no need to imply that the WFK documentation is more complete, but it's welcome to point to it for users looking at the similar technology as it's used when integrating (instead) with Hibernate or JPA applications.
