Hugo: add searchTerm option to search shortcode

* Add searchTerm to example page
* Pass searchTerm from search shortcode,
through search partial, to filter partial
* Set initial searchItem with search filter

To test:
* Navigate to /examples/shortcodes/search and verify that the search results are accurate.
