Custom search bar – search in a specific category/tag field
I want improve on my website some search bars for search a specific post in only one category or tag.
For example i have a page with 200 posts, eachone have one or more tags/catgeories: tag “x”, tag “y”, category “z” and “p”… ; i want make a search bar that in this page can search the post only in a sepcific category or with a specific tag
I don’t want that there is a menu for choose the tag or category because isn’t fine for my website. the clients must only put one or more key words and automatically the search bar serch the text in specific category or tag field that i chose during the construction of my web site.
some one have some ideas to make this or know some code/plugin that could do this?
thanks a lot to everyone that can help me
