When escaping a String like 

+423asdAS/kasd/

with SolrUtils::escapeQueryChars ( string $str ) like this:

SolrUtils::escapeQueryChars ('+423asdAS/kasd/');

and then searching with it, solr returns:

"error":{
    "msg":"org.apache.lucene.queryparser.classic.ParseException: Cannot parse 
'somefield:\\+423asdAS/kasd/': Lexical error at line 1, column 63.  Encountered: 
<EOF> after : \"\"",
    "code":400}}

Workaround:

str_replace("/","\\/",SolrUtils::escapeQueryChars ('+423asdAS/kasd/'));
