Hi dajuanenonli,
There are some troubleshooting steps, which if you haven't done yet, may help:
1. Restart your iPhone: Restart your iPhone - Apple Support
2. Manually update those third-party apps: How to manually update apps on your Apple device - Apple Support
3. Settings > Siri & Search > Scroll down to the apps which aren't coming up correctly when searching > Scroll down to "While Searching" section > Tap on app > Verify "Show App in Search" and "Show Content in Search" are both enabled for each app.
If you're still getting the same results, and since the Apple Maps app comes up as expected, but the third-party apps do not, the next step is to contact the app developer, so they can take a look at what's happening.
