Trending hashtags returning few results

Summary

Trending hashtags returning no or few results. There may also be an issue with caching.

Steps to reproduce

1. Go to discovery feed
2. Hit the text trending on the sidebar
3. Observe none or few tags load.

Platform information

Cross-platform web

What is the current bug behavior?

a) Few or no tags are returned. b) Though the code shows otherwise, it appears as if null values are cached.

What is the expected correct behavior?

Null values should not be cached (check this is the case), and there should be more tags returned. Maybe the abstract bar for what constitutes a trending tag is set too high.
