Wildcard search problem

I am having issue with kibana's wildcard search.

My input docs in kibana:
{Behavior:The program xyz.exe is working}
{Behavior:The program pqr.exe is not working}
{Behavior:The program abc.exe is not working}
{Behavior:The program foo.exe is working}

I want to list down all docs where program is working.

Expected result:
{Behavior:The program xyz.exe is working}
{Behavior:The program foo.exe is working}

I tried in search bar on the discover page of kibana 4.1:
Behavior : "The program * is working" --No result found
Behavior : The program * is working --All found (broad result), it is actuall dividing each word of query

If i search like:
Behavior : "is working" -- Expected result, but it would not be accurate.

My "Behavior" field is "analyzed"
Kibana 4.1

Check out this thread: How to create a query with the wildcard

Maybe you can try a proximity search instead of a wildcard search instead?
