Hibernate Search has a classloading issue that prevents bridges, such as Apache Tika, from being used on indexed fields. This effectively prevents Search from supporting full-text-search on file content.
Workaround: Deploy Tika Parsers as a module -- example: https://github.com/ArtificerRepo/artificer/blob/master/installer/src/main/resources/updates/tika-module-wildfly8.zip Then, directly in HSearch's module.xml, add: <module name="org.apache.tika" slot="1.4"/>
