Are you not seeing yourself or some of your Tweets in Twitter Search? This page will help you figure out why:
If your account does not appear or has a low ranking in user search results:
Twitter user search surfaces results with preference to those users who have a complete name, username, and bio on their profile.
It is also important to Tweet, retweet, and mention regularly to gain resonance amongst your followers so that search results are up to date.
Please note: Though user search results are updated daily, it may take a few days for any changes to your name or username to affect results for a given search term (It takes time to build a new reputation, after all).
New accounts may take a few days to start appearing in user search.
If some of your Tweets or hashtags are not appearing in search:
If you don't see your Tweets appear under the Top search results, select All from the drop down menu on the search results page.
If only some of your Tweets appear, or if you're missing a few tweets, don't fret – we're working to get as many Tweets into Twitter Search as possible.
Due to resource constraints, not every Tweet can be indexed in Twitter Search.
Our engineers are always working to index more updates, but we can't force individual, missing Tweets into search.
Rest assured that your followers will still see all your updates and @mentions, and we'll update on this page as we improve this issue.
