You may need to use ngrams. http://lucene.apache.org/java/3_0_3/api/all/org/apache/lucene/analysis/ngram/EdgeNGramTokenFilter.html
Another option would be doing wildcard query without enabling leading wildcard search. search for cr* and not *cr* as the auto suggest feature should give suggestion for words after "cr" and not before "cr".
