set_column_search_string (name: COLUMN; value: STRING)
Limits the contents of the current query to items whose column name matches (case-insensitive) the string value.
Suppose you have a list of 10 questions, each of which specify easy, medium or hard for a property difficulty. Specify this property in EML, like this:
<question difficulty = "easy">
</question>
Suppose also that 3 of these questions have specified their difficulty as easy. If you want to make the current query hold only those 3 questions, then call this function from script, like this:
script load_easy_questions is set_column_search_string ('difficulty', 'easy') end
