Search feature should support searching by word surrounded by underscores

[hungphan227]

Assume that I have an email in the mailbox with title the_lord_of_rings. If I search by word "lord", there will be no results.

It seems that when creating indexes, we do not separate words by underscore. Should improve this.

(Feedback from Linagora VN HR team.)

Likely we need to modify the analyzer if we want to go with this.

I think it's a valid concern, but quite a change of behavior on the search analyzer yes.

Maybe that could be a good occasion for you @hungphan227 to start a discussion on the mailing list perhaps?

Piece-mealed here. I am dubitous about the legimity of this request.

Why write "lord_of_the_ring" if it is asked to work as "lord of the ring"?

I pretty much bet that the next thing poping up is "I search lord_of_chocolate, why it matches lord_of_the_ring".

A lot of burdon for a niche usage. I'd wait to have convergeant feedback to implement it.

FYI today we support extracting words out of hyphen -.

lord-of-chocolate => Today we can search lord and likely return lord-of-the-ring also.

But we dont for _.

I am dubitous about the legimity of this request.

The use case was searching for candidate name e.g. from mail with subject CV_Nguyen Van A_2024.

I tested and Gmail supports this use case.

However I am not sure if we should support it.

Let's wait convergent requests ;-)
