In Procedure 4.2. - "Configure the Query Module for JBoss Data Grid":

Point 2: It is not clear what properties should be set in infinispan-module.properties file;

Point 3: It is said that the following configuration should be placed in "Infinispan Query XML file for JDG". What file do you mean? It is not clear for the reader.

Point 3 - Code snippet: 

Currently the snippet looks like: 

<property name="[default|<indexname>].directory_provider infinispan"
          value="filesystem" /> 

<property name="default.directory_provider"
          value="/var/lucene/indexes" /> 

If this code snippet refers to the configuration of the indexing for the cache, then from my point of view it should be:

<property name="[default|<indexname>].directory_provider"
          value="filesystem" /> 

<property name="[default|<indexname>].indexBase"
          value="/var/lucene/indexes" />
