I don’t think this has anything at all to do with the Moxie theme.
If you add this to your ‘robots.txt’ file…
Disallow: /search
…it asks bots, crawlers and spiders to not access anything within the ‘search’ folder in the root of your web space.
I have no idea why you have a ‘search’ folder in the root of your web space, it is not put there by the Moxie theme, and neither does WordPress add a ‘search’ folder. Perhaps you have installed a plugin that adds that folder?
If you need to, you can disable the WordPress search functionality with a plugin. Like this one, for example → https://wordpress.org/plugins/disable-search/
Though I’m pretty sure that will not help with your issue.
As I say, this is not a theme issue. The best places to ask about this will be in the appropriate WordPress and Google support forums…
WordPress support forums → https://wordpress.org/support/welcome/
Google support forums → https://productforums.google.com/forum/#!home
If there is anything else about the Moxie theme itself you need help with, please just let us know. If you can’t find a solution using the forum search please create a new topic for each separate issue and we’ll do our best to help.
Please try to remember to start a new topic for each separate issue that you have. We like to keep each topic in the Help Center focused on a single subject. We find that separating each question into a separate topic keeps the information much clearer and easier to follow. Also, it really helps other users to find information and it prevents threads from wandering down Tangent Lane. If you can’t find a solution using the forum search, please always create a new topic for each separate issue that you have.
Thanks.
