Is there any configuration or option to return search results for the "Did you mean" option when there are zero results. Currently when no results come back the user needs to click on the "did you mean" link to redo the search?Can do this via the API - but still means making 2 calls...
The closest you'll get to this is to enable query blending on your collection using the SPEL blending source. This should basically give you the behaviour that you're after.
This is great - thanks! I can also see the "qsup" data coming back in the API also so we can control how this is rendered to the user.
Yes, the qsup element will be populated if query blending occurs, and it will hold the value of the blending that was applied.
