search in responses of surveys

You can search in the following ways.

id:ID - replace ID with response id

author:AUTHOR - replace AUTHOR with user display name or username

Without above format, the plain text search will search all responses in the following columns:

• User display name
• username
• Country
• City

Okay. So no search in field "Title". That is a pity.. 

No. If you need to search the responses of a particular survey, you can go to the reports section of the survey and access the responses list from there.
