WordPress Search in Tags, Categories, Taxonomies and Meta Keys

WP Extended Search is lightweight search plugin for WordPress. It has smooth and simple search settings to modify default WordPress search query.

Key feature of plugin is it gives the ability to select Meta keys, tags, category and custom taxonomies so admin can choose single or multiple Meta keys and taxonomies to include in search query. For instance if admin wants to include a meta key Location which have terms like loc1, loc2, loc3 then admin can only select this meta key to include in search results and if user put loc1 in search query then the posts related to loc1 will comes up.

  • Search in selected meta keys.
  • Search in selected in-built or custom taxonomies.
  • Search in post author name
  • Include or exclude any public post type.
  • Control whether to search in title or content or both 
  • Exclude old content from search results (Older than admin specified date)
  • Customize the number of posts to display on search results page

  • Settings have OR relation with each other. For instance if user searches for "hello world" then both words or any word (You can customize this relation since version 1.1) should be present in title or content or tag or category etc whatever options are selected.

  1. Hello

    How can I use your plugin in this way ?

    1. Hi,

      Currently query string is not supported yet.

  2. How can you set the plugin that search only shows pages an posts that have the tag name.

    I have checked tags in the settings, and removed the ticks next to search in title en search in content.

    1. Hi, You can only set search in tag and post type to post and page. Then someone will search for tag the posts/pages will comes up with that tag. Currently you can not limit the search to posts/pages those have particular tag. Also i kindly request you to please post on forum for furture queries for better support.

  3. how can i search from a particular post?

  4. Hi bro,
    Can i use both default search and this search at the same time? . Because i want to use default search for 1 custom post type and this plugin for the rest of custom post types

    1. Hi John, Well this is kind of feature request on which I am already working. Please open thread on forum so I can provide your solution for now.
