Grammar rules to match string with . and no space as single word

[techpranav]

Hi,

I have a two requirements in same parser like below.

add column S-V.1 ;
print column Test select property.name;

Here , in first query S-V.1 should be treated as a single word which can be acquired with [A-Za-z0-9:!@#$%^&*_\/-.]

In second query, property should be treated as separate field and name should be treated as a subfield of property.

If I write separate rule to match this scenario, it still considers it a single word.

Any solution to this problem?
