The Lock Icon technique employed in the demo is File Maker Pro 13 only.
If you are working with an earlier version, substitute the Base64 Encoded text with links to a set of global icon fields, or omit the icon and simply use the text field ‘Locked’. I did this by selecting the default Data Entry Only and clicking Duplicate.
When I enter one of these operators in the field and try to search, Filemaker gives me a validation error and says that the field contents has to be numerical. I would not consider Find Mode a data entry mode so you'd think the validation rules wouldn't apply.
I don't remember running into it in previous versions, but it could be there too.
All that said, you could use a calc field as a work around.
Crate a calculation field in the same table and name it yourfieldname SEARCH, e.g.

At a higher level, you might be storing a recipe for mixing ratios of oil and vinegar, where the total of the two parts must equal 100%.The number of related records shown at the bottom of the portal below can be derived using script step will take you from the record you’re currently browsing to its related records on another layout.It’s extremely powerful and useful, but there’s a catch.A database developer architects a solution with some expectations on how business information will be structured.He or she might even define rules about the type of data and related information that should be stored.
