OCR issues

Eggplant OCR is not able to search the text every time…if I give the entire screen for reference image it can able to search the text in middle of the screen only, but not able to search the top level and bottom level text.
If I run the script for 10 times 8 times getting failed.

Here i am using some commands :

Click (Text:temp1, SearchRectangle:("Topleftimage","Bottomrightimage"),validcharacters:temp1,ignorespace:on,contrastcolor:white,contrast : on)

Note:- temp1 is variable

Please suggest me some useful commands to searching for text .
