positive.code:   <h2> Combining More than two terms</h2>
    Any number of single or multiple word search can be combined using " and " and " or ".
    <h3> Survey search </h3>
    If both " and " and " or " are used in a single search then the " and " terms take presidence over the " or ".
    For example search "age and when or weight and height", will search for all variables that have both the words age and when.
    Then it will search for all variables that have both weight and heigth.
    The result is the combination of the two searches without duplicates.
    <h3> Other searches </h3>
    Using both " and " and "or " in the same search is not supported and can lead to unexpected results.
