Andrew
I figured out the problem was enclosing <a4j:region> tag for Search Button.
i.e. if we have a4j:region tag then click of search button is not submitting
the search input textfield value to the form & hence the query use to return
no records
When i remove the a4j:region tag , the query returns the records but still
it behaves the same way i.e. it doesnt display search results on first click
of search button
