Star rating filter not working as expected

[javipus]

Filtering by star rating misbehaves when I use quotes in the search term.

Example:

• https://metaforecast.org/?query=%22lab+leak%22&starsThreshold=1 shows no results
• https://metaforecast.org/?query=%22lab+leak%22&starsThreshold=3 shows 5 results (all 3 stars, all Metaculus)
• https://metaforecast.org/?query=%22lab+leak%22&starsThreshold=4 shows one result (4 stars, Rootclaim)

Ok, I'm looking into this. I am setting this as "won't fix", because

• it's relatively easy to try different search terms, e.g., COVID lab leak,
• it would require too much effort on my part.

However, note that metaforecast is open source, so if you are very motivated by this issue, we accept pull requests
