Gmail – How to search only in chat history in Gmail

I have invited contacts to Google chat in 10 min with this. Here is the procedure to do it in smart way,

1. Go to gmail web interface.
2. Click on contacts.
3. Search for 'gmail.com'.
4. Now you will get list of all contact who have gmail.com in it - Click on 'select all'
5. Create group - name it 'allgmail' (You can name anything you want).
6. Compose a new email
7. Type allgmail and press enter. You will fine that all the contact who has gmail.com is listed in TO: field.
8. Now copy all these contact.

9. If you are using Linux/Unix: If you have installed Gedit Open Gedit, paste it in gedit and save file as a.txt. Apply this command in Gedit:

   cat a.txt | sed -e 's/,/,\n/g' | sed -e 's/".*"//g' | grep -i @gmail.com > b.txt

   If you are using Windows Then you will have to download CYGWIN Install it and place the a.txt in the root folder of CYGWIN(where the installation folder is) .Run the exact same command in Cygwin Terminal.

   This fill filter out unwanted character from a.txt and save into b.txt.

10. Now open b.txt. You will find all contacts who have @gmail.com in it.

11. Send them invitations.

Hope this helps.

I figured out how to get a filter to keep chat logs from appearing in the inbox. Create a filter with the following logic in the "Has the words" section:

is:chats

Anything matching this filter should "Skip the inbox" as its action. Problem solved!
