ContentsExprSpanFile Property

Flag indicating whether or not the ContainingText expressions should be matched across the whole file and not just the line.

Property Value

True if the expression should be matched across the whole file, otherwise False if the expression should be matched across just the line.

Remarks

This property is only valid if the containing text expression type is Boolean (i.e. ContentsExprType = ExpressionType.Boolean). If any other expression type is chosen this flag is ignored.

Usually the search engine matches an expression on a line by line basis, i.e. each line must individually satisfy the expression to be considered a match. By using this property a Boolean expression can be matched over a whole file, allowing each line to partially satisfy the expression until the end of the file when the whole expression is evaluated using the partial matches.
