Search results issues related to recent WAF and DOS updated documentation

Describe the bug

When performing a search on the NGINX documentation site, "old" documentation relating to NGINX App Protect v4 and v5 is being returned in the results, but not content related to the new unified and rebranded F5 WAF for NGINX and F5 DoS for NGINXcontent.

To reproduce

Steps to reproduce the behavior:

1. Search for a keyword that should definitely return WAF content, such as policy. Example search query
2. View the left-hand navigation to note that NGINX App Protect WAF content is returned, but not F5 WAF for NGINX content is not.

Similarly, for DoS content if you use this example, you will observe that similar behavior is occurring for F5 DoS for NGINX content.

Example screenshot for WAF:

Example screenshot for DoS:

Expected behavior

NGINX App Protect WAF content should no longer be returned, but F5 WAF for NGINX should be.
