Hello Phil,
We Appreciate your quick reply.
Based on the description you provided in the reply, it appears that this issue could occur if Library folders which are moved to different drive are not included in the search index and that could be a reason why the apps are not able to search for files.
I would suggest you to try the following methods and check if that resolves the issue.
Method 1: Run the Search and Indexing Troubleshooter
This troubleshooter is an automated Windows 8.1 inbuilt tool which finds and fixes the common issues with the
Search and Indexing feature of Windows 8.1. Perform these steps to run this tool and check if that helps.
a) Press “Windows Logo” + “W” keys from the keyboard.
b) Type “Troubleshooting” in the search bar and press “ENTER”.
c) In the “Troubleshooting” window, click on “View All” on the left pane.
d) Click on “Search and Indexing”.
e) Click on “Advanced” and then click on “Run as Administrator”.
f) Click “Next” and follow the on-screen instructions to complete the troubleshooting process.
Please check the troubleshooting report and let’s know the details. You may also try the suggestions given by the troubleshooter and check if that resolves the issue. If that doesn’t help, then try the next method
to rebuild the Windows 8.1 Search Index on the computer and check if that resolves the issue.
Method 2: Rebuild Windows 8.1 Search Index
Before you rebuild the Windows 8.1 Search Index, you should make sure that the indexing is turned “ON” in the computer and then follow these steps.
a) Press “Windows Logo” + “X” keys on the keyboard and select “Control Panel” from that list.
b) Select either of the options: “Small icons” or “Large icons” from the “View by”
menu on the upper-right corner of the “Control Panel” window.
c) Click on “Indexing Options”.
d) Click on the “Advanced” button at the bottom of the “Indexing Options” window. This displays a new window
titled “Advanced Options”.
e) Click the “Index Settings” tab, if it isn’t selected already.
f) Click the “Rebuild” button to delete and rebuild the file index.
g) Click “OK” to confirm.
Now, try searching within the apps and check if you are able to get the desired results. Please get back to us with the updates.
