Hi,  
How do I enter a regular expression in kibana filter.  
I have a document which looks like  
{ Name:User details, Status:failed, InstanceName:Windows volume maintenance tasks, Domain:TEST.COM }

Now I want to set a filter for the InstanceName so that I get only the InstanceName with "Windows" string.

I tried giving InstanceName: _Windows_ as well as InstanceName: Windows\* in the Search Field of Discovery in kibana but it doesn't work.  
Kindly guide.

Thanks & Regards  
Sunil

In [Lucene query syntax](https://lucene.apache.org/core/2_9_4/queryparsersyntax.html) you don't need a space between field name and value. Try InstanceName:Windows\*
