Hi Udhay,
a) I would recommend to record the actions (select script recording but not keyword test recording (

b) Do you really need to use the Ctrl-F functionality? Are you testing the Find dialog? If not, then why not to get the contents of the target page as a text (use the Object Browser to find the property that contains the contents of the tested page as a text) and then use the string functions like StrContains() to check if the page contains the text you are looking for.
