Insert a style into your CSS to limit the width of the input:
input[type="search"]{
max-width: 80%;
}
The selector input[type="search"] takes the default Datatables search element. Adjust the value of 80% more or less as it does not pass the panel.

Try this on your CSS:
input[type="search"]{ max-width: 10%; }... the intention is to leave too small to see if it has any effect... then you increase this value of 10% until it is in the ideal size.– Sam
