Topics are search words that the Search Cartridge expands, resulting in a search query. The generated search query combines the search expressions that previously have been defined as belonging to this topic.
In the simple parser topics are recognized even if the TOPIC operator is not specified. In the explicit parser each of the following formats can be used to specify a topic in an expression:
{topicname}
<#TOPIC>topicname
<#TOPIC>(topicname)
In the examples above, topicname is the name of the topic to be used in the expression.
