Summary: tologx/query-engine - probs with value-like

Initial Comment:
I try to perform a value-like - query. Therefore I wanted to 
register a FullTextIndex. My Problem: How can I do this:

At first I need an IndexProvider, which I can initialise 
with my topicMap. After that I have to register the 
IndexProvider in the TopicMap's IndexManager.

How can I get an IndexProvider?

Thank you!!
So far it's working now. My next problem is to perform a 
query. I tried to perform this one (from 
accountingontology.com):

select $TOPIC from topic-name($TOPIC, $NAME), value-like
($NAME, "test") ?

and get the following stack-trace:

org.tm4j.tologx.TologParserException: Error parsing query

You need to instantiate the class
org.tm4j.topicmap.memory.index.LuceneFullTextIndexProvider,
and then pass that instance into the registerIndexProvider
method on the IndexManager.

Note that you need to pass a Properties instance in to the
constructor of the LuceneFullTextIndexProvider. The
properties that are recognised are documented in the class
org.tm4j.topicmap.index.text.LuceneIndexBase
