Can't reblog tag-searched posts from Blog View- also re-indexing is Improving general site search overall☺

The good news: Re-indexing is improving general site search- yay! More results now, hopefully many more in the future :) 

The other news- while waiting for Re-indexing, I'd been using tag search in Blog View - on my own blog and other blogs. As I recall  this method was working up to a couple weeks or so ago (best guess). It no longer does, unfortunately. 

I can find content using tag search on my own and others' blogs- in Blog View-   but i can't do anything it with it. It  won't rebog, queue or save to drafts. When I try to do one of these actions, it appears to happen but doesn't actually happen. e.g. the reblog doesn't reblog, if i choose queue it doesn't go there, if i choose drafts, it doesn't go there.  

Straightforward non-searched posts Do reblog from blog view. I get the little confirmation notice and they post wherever I direct them. Tag-searched posts don't. No confirmation notice and when i check wherever - they aren't there. 

Is there something wrong with my blog? Or is this a sitewide issue? 

Tag search from the dashboard Does work, but it's not efficient (for me). It pulls up all results for a tag and if (for example) someone has uploaded 100 photos with a particular actress or whatever tag, i have to scroll through all of them to get to other results. This bulk uploading with a single (relevent) tag does happen, more than you might think.... 

 Best search methods -for me- are general site search (esp when all content is fully re-indexed) and secondarily Blog View search...currently down on my blog. 

I also use side blog search, which works well for single tags but will only display about 10 results, as  I believe it always has. 

Any info or help much appreciated ☺

Thanks!.
