**Hi ,**  
I have a bunch of students records in my database(MySQL) and i want to pull those to elastic search which matches my pattern . Now i need to write a configuration file for this .I'm clear about writing input and output plugins.  
But I don't have much idea in writing the grok filter plugin even though i visited the documentations.

my pattern : **g^[a-zA-Z]** (Accepts names that starts with g)

field name in my table : **Student\_Name**

**Can any one help me to frame the filter plugin ??**
