The simple answer is that you can't search for a quotation mark. You also can't search for a lot of other punctuation. From my experience Gmail interprets most punctuation as a space and anything joined by punctuation to indicate that the strings should be side by side. In fact multiple spaces are not an issue it is the strings that Gmail seems to focus on.
Perhaps that doesn't matter. Do you really need to find the quotes specifically? Is there a concern about false positives such as
and then james said come here
Your search could be any of
"and then james said come here"
"and then james said .come here"
"and then james said..come here.."
You could drop the quotation marks entirely and use periods to search for the terms as a group
and.then.james.said.come.here
Basically they all say the same thing: Search result must contain ALL these strings and they must ALL side by side in this order.
Let me know if I can help further.
Note about your question
Issue is when I put that around quotes
"and then james said "come here""
It creates two exact phrases search:
- and then james said
- come here
This is not actually accurate
what it creates is 1 exact phrase 'and then james said' then also looks for 2 words: "come" and "here" which can be anywhere.
The following could be successfully returned:
Here lies James. 6 feet below. Dad said come, and then James said no.
