Which filter type is used for free text input?

• A. Textbox filters
• B. Boolean filters (yes/no field types)
• C. Numeric filters
• D. List filters

Answer: (A)

Free text input needs a filter that accepts any characters the user types, not a restricted set. Textbox filters are designed for this, offering a plain text field where you can enter words or phrases and search on them. The other filter types constrain input to specific kinds: Boolean filters only allow true/false, numeric filters require numbers (often with ranges), and list filters restrict choices to a predefined set of options. Since free text doesn’t fit those restricted formats, a textbox filter is the appropriate choice.
