Since version 4.4 Datafari comes bundled with a help page that can be accessed through a link on the top right of the index and results pages:
This help page by default contains some basic information about the search capabilities of Datafari and some of the tools available to perform more advanced queries.
The content of this page can be edited through the admin interface. The edition panel is available in the search engine configuration section as shown below:
To comply with the format of the search page, each section title should be an header 2 (<h2> tag in html code).
Then use paragraphs (<p> tags) to include text. You can also include images, tables, links, ...But do NOT use div tags.
You can use the "show code" button to edit the page as html directly if you are comfortable with it. It is at the far right end of the editors control panel.
Anything between two h2 tags will be hidden when the help loads.
Only the h2 tags are visible and when clicking one of the titles, the associated content is displayed (and hidden again if the same title is clicked again).
