• This search is case in-sensitive. 
• It only searches on the property value and literal property value.  
• A leading and trailing wild card is added to the each token in the search text.
• The literal property part (without the wild cards) of the query is boosted by 50.  This gives a literal match priority.
• Parsing is done with Lucene's StandardAnalyzer.
