I have a use case where i want to tokenise emailId with starts with filter along with punctuations.
for example. email - **[ona.ki@gl.co](mailto:ona.ki@gl.co)**
I want to know whether the the following matches for the above is possible to achieve.
on, ona, ona., ona.k, ona.ki, ona.ki@, ona.ki@g, ona.ki@gl, ona.ki@gl., ona.ki@gl.c, [ona.ki@gl.co](mailto:ona.ki@gl.co)
.k, .ki, .ki@, .ki@g, .ki@gl, .ki@gl. , .ki@gl.c, [.ki@gl.co](mailto:.ki@gl.co)
ki, ki@, ki@g, ki@gl, ki@gl. , ki@gl.c, [ki@gl.co](mailto:ki@gl.co)
@g, @gl, @gl. , @gl.c, @gl.co
gl, gl., gl.c, [gl.co](http://gl.co)
.c, .co
co
Use case example for **[ona.ki@gl.co](mailto:ona.ki@gl.co)**
**ona.k** - _should match_
**na.k** - _should not match_
**.ki@** - _Should match_
**ki@** - _Should match_
**i@** - _Should not match_
The reason why i want to tokenise this way is because consider there are 2 doc with text values
1. [ona.ki@gl.com](mailto:ona.ki@gl.com)
2. [mona.gh@gl.com](mailto:mona.gh@gl.com)
When the user types on, ona, ... i want to fetch and show only [ona.ki@gl.com](mailto:ona.ki@gl.com) not the other one.
Thanks in advance
