Add Weight to Entries (posts) within a Specific Category (taxonomy term)

By default SearchWP considers the actual content of taxonomy terms when performing searches. Depending on the way you’ve set up your site, you may want to give extra weight to entries regardless of taxonomy term, but instead add the weight to all entries that have been given a specific taxonomy term.

All hooks should be added to your custom SearchWP Customizations Plugin.
