  1. Upload indextank/ to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to the ‘Tools’ -> ‘Indextank Searching’ menu in WordPress
  4. If you have an account, enter your data and hit ‘Save’. If not, hit the ‘Get one’ button.
  5. Hit the ‘Index All posts’ button

You are all set, now just query something on your blog sidebar. If the results don’t look nice with your template:

  2. Hit the ‘Magic’ button, on the ‘Look and Feel’ section


  • Q: Do I need to get an account on to use this plugin?

    • A: Not really. The plugin can get an account for you, from your dashboard.
  • Q: Is it FREE?

    • A: Yes, until you get 100,000 posts it is. If you ever go over that limit (a lot of blogging!) you may have to upgrade.
  • Q: Are there any knows issues with other plugins?

    • A: Not really. This plugin calls apply_filters('the_content', $post->post_content), so if there’s a buggy filter you may see errors while indexing. If that happens, please let us know at support (at) indextank (dot) com
