Hi team...

Kindly help me sort out this:

When I search for an item on the OPAC without specifying if I want to
search by title, call number, barcode number etc it show no results have
been found but if I specify either the title, call number, barcode etc it
shows the item...

How can I sort this such that it searches without having to click on the
drop down box to choose the search option?
