Search targets containing underscores?

I’m documenting some SQL queries, and want to be able to search for column names that have underscores in them. However I haven’t been able to get DevonThink to search for these as a single item. For example, instead of searching for Address_Line_1, it finds all occurrances of Address or Line or 1. Is there some way to get DevonThink to treat these underscores as part of the string?

I tried quoting the string with single- and double-quotes, and quoting the underscores with backslashes but no luck.



Underscores aren’t indexed but switching to phrase searching will also find Address_Line_1.
