如何在搜索结果中显示特定类别

Question

How can I display search results in a specific category? e.g When searching for word 'articles', search results should display category 'Articles'.

Answer 1

It should be possible to create this feature with the post_search wordpress filter.

See: https://codex.wordpress.org/Plugin_API/Filter_Reference/posts_search

The post_search filter is executed before the category check so you should be able to set the category in the query based on the search terms. Beyond that it is a matter of adjusting your template(s) to display the category used by the query.
