Tag over summary

[qutorial]

Now tags are prioritized by the relevance algorithm over summary.
In other words, when there is a tag on vulnerability, the summary is ignored completely.

If somebody tags a relevant vulnerability with a wrong tag, maybe maliciously even,
then the vulnerability will disappear from the relevant vulnerabilities list.

Need to think about the algorithm again and suggest a solution.

Giving the user a choice is a solution probably?
By default we keep tags and summary matching.
