Hi,
By preview I mean the description as activated in the options of the smart search component , the 255 characters by default that come from the introtext/fulltext apparently.
The search results have the title, description and optionally the url of the page.
I tried with Seblod content plugin as first but no luck. It seems to happen only for groupX, select dynamic and select dynamic cascade values.
Interestingly it starts at class or id (without the first '<') and stops at the '>' bracket of the html element. then it displays the values properly.
Regards.
