Hi Vishnu
Thanks for asking this question.
Filter with contain does the substring match. Meaning it will find records with content such as this:
This is matchwithsubstringcontent
because it has a value where there is a mention of string
The second command won't do that. The search command does a token based matching by default. It will filter only for specific cases of string. A comma or dash seperated string will result in final record.
For example, if the record has something like: `a string` or `this should match because-string`, it will be in the output.
search content ~ "*string*" is more close to your filter example.
