We have a responsive html5 output. When I search a term the search results appear in the left navigation. The topic title displays with a short one liner about the topic. Do you know from where this text is taken. How does it appear and can this be changed or hidden?
IIRC, it comes from the topic properties page text.
The summary (or context) comes from the first X number of characters in the topic. You control this in the Responsive HTML5 SSL output settings. Select the Search settings in the SSL output config dialog. To increase or decrease the amount of summary included, edit the "Number of Characters in Search Context" field. To suppress the summary altogether, remove the checkmark from "Show Context in Search Results".
