Components Help Screens
From the administrator area, select Components → Smart Search from the drop-down menu of the Administration screen, then click on the Content Maps menu bar item.
This screen shows the content maps currently in the Smart Search index. Content maps allow you to cross-reference your indexed content (articles, etc) to related meta information such as the category in which it resides. Each content item that is indexed by Smart Search is added to one or more content maps that can be used as filters when searching the index.
Content maps are split into two parts:
These branches and nodes are what make up the advanced search panel available on the front-end. For each branch there can be a drop-down select list and the nodes are added as values to the respective list. More advanced site builders can override the default layouts and use multi-select lists or checkboxes instead.
It's important to note that branches and nodes from different content types are merged into the one list. A Joomla article in a category called "News" and a news feed or contact in a category named the same are mapped to the same node in the same branch. This is a little like tagging different types of content with the same label. The effect is that your site visitor does not have to know how your content is classified in order to set the correct filters to find it.
The content maps screen shows all the branches within the Smart Search index together with a number indicating the number of nodes within that branch. Clicking on a branch title allows you to see the nodes within that branch together with the number of content items that belong to that node. A content item can belong to multiple nodes within a branch as well as to multiple branches.
At the top right you will see the toolbar:
The functions are:
Enter part of the title of a branch or node and press the Search button to find matching branch or node. Press Reset to clear the search field and restore the list of content branches or nodes.
In the table containing the indexed content for your Joomla! site you will see different columns. Here you can read what they mean and what is displayed in each column.
