You might be able to make use of the dictionary compound word filter, but
you will have to build up a dictionary of words to use:
http://lucene.apache.org/core/4_5_1/analyzers-common/org/apache/lucene/analysis/compound/DictionaryCompoundWordTokenFilterFactory.html
My e-book has some examples and a better description.

Hi Adnreas,
If you don't want to use wildcards at query time, alternative way is to use
NGrams at indexing time. This will produce a lot of tokens. e.g.
For example 4grams of your example : Supertestplan => supe uper pert erte
rtes *test* estp stpl tpla plan
Is that you want? By the way why do you want to search inside of words?
<filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="4"/>

I suppose i have to create another field with diffenet tokenizers and set
the boost very low so it doesn't really mess with my ranking because there
the word is now in 2 fields. What kind of tokenizer can do the job?

I am querying "test" in solr 4.3.1 over the field below and it's not finding
all occurences. It seems that if it is a substring of a word like
"Supertestplan" it isn't found unless I use a wildcards "*test*". This is
write because of my tokenizer but does someone know a way around this? I
don't want to add wildcards because that messes up queries with multiple
words.
