Thank you so much, Jody, for the thorough reply. I was initially averse to using a function on the adr_label since I fear it would prevent database indexes on the column from being used… but then I realized I’m already using an strToLowerCase in my real code (though not my example here), so I suppose it may be a moot point 😊
Thanks again, this is exactly what I was looking for!

Looking a little more at java Pattern (https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html) matcher used: - The newline character is special to the java pattern matcher, so support would need to be added to LikeToRegexConverter - The pattern matcher has a flag for MULTILINE which is not used So you are not missing anything, support for multiline is not implemented / available. As a workaround I suggest doing a string substitution using <https://docs.geotools.org/stable/userguide/library/main/function_list.html#strreplace-string-search-replace-all-returns-string> function call on your adr_label and pass the result to PropertyIsLike Jody
