Big Problem with special characters

[Kraus, Ralf | pixelhouse GmbH]

Hello,

first some details about my SOLR installation:
schema.xml

   <fieldType name="text_test" class="solr.TextField" 
positionIncrementGap="100" >
       <analyzer type="index">
           <tokenizer class="solr.WhitespaceTokenizerFactory"/>
           <filter class="solr.StopFilterFactory" ignoreCase="true" 
words="stopwords.txt"/>
           <filter class="solr.LengthFilterFactory" min="2" max="50" />
           <filter class="solr.LowerCaseFilterFactory"/>
           <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
           <filter class="solr.SnowballPorterFilterFactory" 
language="german" />
       </analyzer>

       <analyzer type="query">
           <tokenizer class="solr.WhitespaceTokenizerFactory"/>
           <filter class="solr.StopFilterFactory" ignoreCase="true" 
words="stopwords.txt"/>
           <filter class="solr.LowerCaseFilterFactory"/>
           <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
           <filter class="solr.SnowballPorterFilterFactory" 
language="german" />
       </analyzer>
   </fieldType>

Search:
qf=name^2.0+name2^1.5+name3
wt=phps
rows=30
start=0
sort=score+desc
fl=*,score
q=speed
qt=dismax

When I have a string like "(speed)" in "name3" or "name2" SOLR dont find 
it at all :-( If I search for "(speed)" erverything is fine !
