Excluding certain topics from search results using the search attribute method

The WebHelp Search engine does not index DITA topics that have the @search attribute set to no.

To exclude DITA topics from WebHelp search results using this attribute, follow these steps:

Edit the DITA map and for any topicref that you want to exclude from search results, set the search attribute to no.
For example:
```
<topicref href="../topics/internal-topic1.dita" search="no"/>
```
Save your changes to the DITA map.
Run your WebHelp system transformation.
