How to Display Custom Title in Search Results

It is possible to display a custom title for topics in the search results page. This can be achieved by adding the <searchtitle> element inside the particular DITA topic (or within the topic reference in the DITA map). The <searchtitle> element is used to specify the title that is displayed by search tools that locate the topic. This is useful when the topic has a title that makes sense in the context of a single information set, but may be too general in a list of search results. If the <searchtitle> is specified, then the search results page will display the contents inside the <searchtitle> as the topic title.

For details about the <searchtitle> element (including an example), see https://docs.oasis-open.org/dita/v1.2/os/spec/langref/searchtitle.html.
