cuelang.org: searching for content with named attributes doesn't refine the search results as expected

[jpluscplusm]

What page were you looking at?

https://cuelang.org/search/?q=title:%22case%22%20contentType:%22Concept%20Guides%22

What version of the site were you looking at?

cue-lang/cuelang.org@8cc8808

What did you do?

I tried to search for all concept guides whose titles contain the phrase "case". (I was actually looking for the multi-word phrase "use case", but I've simplified it for this issue, as the problem still strikes)

What did you expect?

I expected (at least) the 5 concept guides whose titles end "...use case" to be returned:

• https://cuelang.org/docs/concept/code-generation-and-extraction-use-case/
• https://cuelang.org/docs/concept/configuration-use-case/
• https://cuelang.org/docs/concept/data-validation-use-case/
• https://cuelang.org/docs/concept/querying-use-case/
• https://cuelang.org/docs/concept/schema-definition-use-case/

I especially expected this because of the contents of hugo/algolia-settings.js:

$ grep -B2 searchableAttributes hugo/algolia-settings.js  
index.setSettings({
    queryLanguages: ['en'],
    searchableAttributes: ['title', 'content', 'summary', 'tags', 'contentType', 'authors'],

What did you see instead?

Only 2 results were returned. One is correct (based on my assumptions about the search page's capabilities) because it is a concept guide whose title contains the term case, and one is incorrect as its title doesn't contain that term. (This is a screenshot of the search term without quotes; the same results are returned if quotes are added (title:"case"))

I expected (at least) the ~6 concept guides whose titles end "...use case" to be returned

For completeness' sake it would be useful to include links to these please: that might be relevant in the investigation.

One correct (based on my assumptions about the search page's capabilities), and one not.

Please can you expand on this as to why one is right and the other wrong?

It's obvious after a close reading, but in the interests of helping others who come to this issue it would be best to make it easier for them.
