• This search is case in-sensitive. 
• It only searches on the property value the untokenizedLCPropertyValue and literal property value.
  
• The literal property part of the query is boosted by 50.  This gives a literal match priority.
• A trailing wild card is on the term (but no leading wild card) and the term can appear at any position.
  
• Lowercase and special characters removed during query parser parse.
  
• Parsing is done with Lucene's StandardAnalyzer.
