Relevanssi adds a shortcode to help making links to search results. That way users can easily find more information about a given subject from your blog. The syntax is simple (just replace the angle brackets with square brackets):
This will make the text John Doe a link to search results for John Doe. In case you want to link to some other search term than the anchor text (necessary in languages like Finnish), you can use:
<search term="John Doe">Mr. John Doe</search>
Now the search will be for John Doe, but the anchor says Mr. John Doe.
One more parameter: setting
<search phrase="on"> will wrap the search term in quotation marks, making it a phrase. This can be useful in some cases.
