Say today is 12/12/2014 and I want to search all mails for Today only in my Primary label in Inbox. I type this query in Gmail search bar:

```
in: inbox -category:{social promotions updates forums}  after: 2014/12/11

```

With this I get all today's emails in my Primary label of Gmail inbox, except for few auto-generated emails, e.g. Amazon.com sending some autogenerated emails etc. Please tell me what modification I should do in my query above to get all missing email threads too in search result.
