How to hide specific tweets from rotation?

Just use the minus sign in your search.

[rotatingtweets search="opimisto -pessimiso"]

Thanks! Do you mean I can just use it like that:
[rotatingtweets search=”-pessimiso”] to remove all tweets that include the word pessimiso?

That way you will get all the Tweets in the world that don’t contain pessimiso.

The quickest way to work out search terms is via https://twitter.com/search-advanced

So it conflicts with “screen_name=”?

Yes. It’s instead of screen name.

(I can’t remember offhand which gets priority if you have both).

It overrides other settings and just rotates the search results, retweets and all, even if retweets are off in the plugin settings. Also it does not work with “-#something” so tweets with specific hashtag can not be hidden (even if we use -%23something). Maybe I’m missing something?

Did you construct and test your search term with https://twitter.com/search-advanced?

If you go with something like:

-#nhshealthcheck2016 from:mpntod

it should work. It shouldn’t include retweets unless you add include:retweets

Hmm it works now… Must have typed something wrong last time.
As usual – you’re the best Martin! Thanks ??

That’s weird – for some reason now I see:

Problem retrieving data from Twitter
No Tweet results for search ...

Yet if I click on the search string I do get results…

The search via Twitter’s API has a shorter search window (i.e. it looks back less far in time) than searching via their website unfortunately.

I haven’t tweeted for two weeks – so you say this is the reason why the API can not show these “old” tweets? Shame on Twitter…

Rotating Tweets normally compensates for this via its own caching. So, unless you’ve changed a setting of some kind (which can reset the cache), this shouldn’t happen.

Ah yes – I cleaned all with WP optimizer. What happens when RT gets its cache flushed? How to rebuild it?

Unfortunately, since WP-Optimize has probably deleted the transient data used by Rotating Tweets (assuming you selected that option), there’s not a lot you can do. Your old Tweet data is lost and gone and can’t be replaced from Twitter.

I can only suggest waiting until there are some more tweets in your search result!

And don’t delete transients! The whole point of them is that they expire and get removed automatically – and you don’t need to be ‘cleaning’ them.
