Hi @Bernd2Heinen,
There are several packages available for chemoinformatics, but one of my favorite is RDKit.
You can use it via Python (and run it with JMP), see "Substructure Searching" on this link : https://www.rdkit.org/docs/GettingStartedInPython.html
Since I'm not a coder (my goal this year is to get to know Python and start using it), you can use RDKit through low/no-code platform like KNIME.
Another option that could be done in JMP directly would be to do a sort of Regex pattern identification script, that can highlight rows containing the same pattern as the one you have in your input/query. In your example from the image, it could be possible to do a sort of Regex search to find all rows in which the SMILES formula contains the pattern "C=1(C=CC=CC1)" for the phenyl group.
I hope this answer will help you,
