Case Insensitive Search for StringField

[Chellasamy G]

Hi,



I can't find any way to perform case insensitive search on StringField. Please 
help me out.





i.e If the field value is "Flying Robots", then the phrases "flying robots", 
"fLying RObots" etc should match the value.





I also need the original case of the field value to be preserved in the search 
results.





Thanks,

Satyan
