Steps to reproduce:
1. Upload a recording with text slides
2. Search for slide text with search rest endpoint
The resulting XML always has hit = false and the relevance is sometimes 0 instead of -1 with no findings.
The resulting XML should have hit = true when something has been found and the relevance is either -1 for not found or greater 0 for findings
