Hey i have a problem when i use a curtain key word in the search bar its not listed in the keywords side dispite their being the content can someone help me fix this?

Can you be a little more descriptive of the issue? What tag are you trying to search for?

If you're saying that you're expecting a tag you search for to appear in the list of tags on the left-hand side of the page, that's not really how that works. The list of tags on the left-hand side of the page are only the currently "Trending" tags; they're the top 30 tags used on posts in the past 24 hours. The tag you're searching for simply may not be a currently trending tag.
