New portal search only returns 3 results per search

Summary

The new service desk customer portal search only returns 3 results per search.

Steps to Reproduce

1. Create a service desk project
2. Create a knowledge base for it
3. Create 4 pages or more starting with How-to
4. Access the customer portal page and search for How-to

Expected Results

The search should return all knowledge base pages containing how-to.

Actual Results

It only returns 3 suggestions.

Notes

This is just an example case but it's visible how much impact it can bring to service desks with big knowledge bases.
The ticket deflection will be highly affected by this problem as the customers must know the entire name of the knowledge base to find it.
