If you want to use a simple search, use the following simple search form . However, if you want to make a complicated search with multiple clauses and conditions, use the Complex search form . This form contains three columns - the first column is an operator column, available only from the second row. The second column is the search string column, with text regions to type in a search string or regular expression. The third column is for specifying the region in which the search string is to be searched for.
