can a search for the individuals in a group display notes instead of address, etc
That might be a little visually difficult if they have 30 notes, but here's two options:


At the search results screen select some or all and then from the actions dropdown at the top of the list choose Export.
In the export screens choose "select fields for export".
When choosing the fields, include the field called "Note(s)".


If you want it on the screen instead of an export, and you're ok with only seeing the first note you can do like so:


Go to Administer - Customize Data and Screens - Profiles.
Click on the Reserved tab.
Click on "Fields" on the right side of the screen next to the Summary Overlay one.
Click Add Field.
For field name, select Contacts , and then the one called "Note".
Click save.
Do a search and in the search results list, if you hover over the contact icon in the 2nd column you'll see the first note in the popup that comes up.
