Under some circumstances, one has to jump through many hoops to be able to enable AI search results.
- have your search “sort by” to latest posts
- have a search query that does not yield any non-AI results (it does give results)
- go to advanced search
- you get no results (feels weird since you did get results on the previous page before switching to advanced)
- and it shows “AI results unavailable”
- it is impossible to turn the AI results on because the sort order is not set to “relevance”
- it is impossible to set the sort order to “relevance” because there are no results
- there are no results because I cannot turn on AI results
The only way out is to
- change the search query so it does give actual results
- that makes the sort order dropdown appear
- set sort order to “relevance”
- enable AI results
- enter the original search query
