When storing the data in the Lucene index, store a document field where the spaces have been removed from the source data – and index that field. When searching, strip the spaces and search on the field without spaces. If the spaces are important in the output, I recommend you also the original data in a separate field of the Lucene document. That way, you can use it for user display after finding the documents with the other field.
