As shown in the figure, mydata.png is my original data, myquery.png is my query interval, result.png is my query result, and my query statement is: ./ query_hint_m.exec -v -m 20 -o all -q CONTAINS -r 10 samples/mydata.dat samples/myquery.qry. Theoretically, there should be three results: 20140928 20180717
20110627 20180717
20140811 20180814, but only one item is displayed in resul.png
