+1. This would be great to have.

I am wondering this is not yet possible... :-(

I'm also interested in this feature.

There is an undocumented way to do it. You can add these parameters to the URL:

f[]=subject
&op[subject]=~
&v[subject][]=texttofind

issues.json?f%5B%5D=subject&op%5Bsubject%5D=%7E&v%5Bsubject%5D%5B%5D=texttofind

Again: this is undocumented and may change without notice in a future version but it solved my problem.

can confirm the solution by Jos Groot Lipman is working, looking for a documented way though...

+1 for this to be implemented as a regular functionality.

Not sure when it appeared, but the direct prefix form of the ~ operator example in note 4 works for me in Redmine 3.4.1:

issues.json?subject=~texttofind

…so I suppose this issue can be closed?

For anyone looking for an answer: the % character works as wildcard in the subject text field
Tested on Redmine 4.0.4

The behavior is going to be fixed in the upcoming Redmine 5.0.0 (#35073). Instead, filtering by multiple keywords (AND search) will be available (#35764).
