Hello SteveJoshua,
You've walked through great steps to help with Spotlight Search on your Mac. In addition to the steps you've tried thus far, have you rebuilt Spotlight index? If not, this can help with resolving issues with Spotlight Search. You can find the steps for rebuilding Spotlight index below, and listed in the following article.
- "Choose Apple menu > System Preferences, then click Spotlight.
- Click the Privacy tab.
- Drag the disk or folder that you want to index again to the list of locations that Spotlight is prevented from searching. Or click the add button (+) and select the disk or folder to add.
- From the same list of locations, select the disk or folder that you just added. Then click the remove button (–) to remove it from the list.
- Quit System Preferences. Spotlight will reindex the contents of the disk or folder. This can take some time, depending on the amount of information being indexed."
