title: Solrnet: problem when search field value is query operator (eq. or, and)
body: <p>To be more precise I will be working with example...</p>
  
  <p>Clean query is: (type:77 AND (zipCode:12345 OR name:OR))</p>
  
  <p>When querying on Solr Admin page this throws exception:</p>
  
  <p>org.apache.lucene.queryParser.ParseException: Cannot parse...</p>
  
  <p>So on Solr Admin page I changed query to:</p>
  
  <p>(type:"77" AND (zipCode:"12345" OR name:"OR"))</p>
  
  <p>which worked as a charm</p>
  
  <p>Now I have a problem to do the same stuff with solrnet. I am using SolrQueryByField class for querying. When I am working with</p>
  
  <p>new SolrQueryByField("name", "OR")</p>
  
  <p>I get Solrnet.Exceptions.InvalidFieldException which is in accordance with Solr Admin page, but when I am working with</p>
  
  <p>new SolrQueryByField("name", "\"OR\"")</p>
  
  <p>I get wrong results. By inspecting network traffic I found out that http get request is different (for brevity only name field name and value are given):</p>
  
  <p>name%3A%22OR%22     => from Solr Admin page</p>
  
  <p>name%3a%5c%22OR%5c%22     => from solrnet</p>
  
  <p>My question is: what sholud I do to prevent solrnet from adding %5C (backslash) to query string?</p>
  
  <p>Thanks in advance</p>
