How to remove a lot of "\n" in text extracted from a Word file using Solr?

Question

when i index a .docx document , with Apache Solr 4.9 (solr cell); it extracts the text with a lot of "\n", is there some way to either clean the field content or remove the "\n"?

field content looks like:

"content": [
      " \n \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n \n   Solr  es un motor de búsqueda de código abierto basado en la biblioteca Java del proyecto Lucene, con APIs en XML/HTTP y  JSON , resaltado de resultados, búsqueda por facetas, caché, y una interfaz para su administración \n    \n  "

here is the code, i'm using SolrJ, java, tomcat 8, Apache Solr 4.9, also i tried to modificate schema.xml, using regex on the tokenizer to replace the "\n" with "" (blank), also another way but however nothing made it work

the code is here :

  SolrServer solrServer = new HttpSolrServer(url, httpClient);
  ContentStreamUpdateRequest up = new ContentStreamUpdateRequest("/update/extract");    
  up.addFile(new File("C:\\doc.docx"),"");
  up.setParam("literal.id", "indexDoc.docx");
  up.setParam("field", "anything");
  up.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);

  NamedList<Object> result = solrServer.request(up);
  String y = "";

  rsp = solrServer.query( new SolrQuery( "id:indexDoc.docx") );
  System.out.println(rsp.toString()); `
