I am using the Kibana 'filter builder' to create a search like 'uri is x'. The uri field (from Bro http logs) contains this: /auth/spGo.php?assetid=home&supportid=

When I set 'x' to one of these, the search works and finds what I expect (note lack of escaping):  
/auth/spGo.php?assetid=home&supportid  
/auth/spGo.php?assetid  
spGo.php?assetid

When I set 'x' to one of these, the search does NOT work and finds nothing:  
/auth/spGo.php?assetid=home&supporti  
/auth/spGo.php?asseti  
php?assetid

I would like to do search for ?, but using \? does not work either.

Bug? Newbie error? Any solutions?

Thanks,  
David

What is filter builder referring to?

Sorry, by filter builder, I mean the "Add a filter +" just below the search box at the top of the "Discover" menu. I am sure there is an official name for this, but I do not know what it is. I have been looking at ELK for about a week and a half, so I have a lot to learn.
