[mumi] [wishlist] Allow searching subject prefix

Recipients:(address . bug-guix@gnu.org)(name . Arun Isaac)(address . arunisaac@systemreboot.net)

Message-ID:871qfaexil.fsf@xelera.eu

Hello,

IMO is useful to be able to search for "subject:foo", it's a different

search than searching for foo in the body

in file mumi/xapian.scm I read:

Toggle snippet (9 lines)

;; Index subject and body without prefixes for general

;; search.

(index-text! term-generator subjects)

(increase-termpos! term-generator)

(index-text! term-generator text)

Is it possible to add such a feature please?

Thanks! Gio'

P.S.: I did not Cc: Ricardo Wurmus since AFAIU he prefers not to

continue developing this

Hi Gio,

Thanks for this feature request! It's always gratifying to know that

someone is using mumi, especially its more advanced features! :-)

It looks like we implement this already. See
https://git.savannah.gnu.org/cgit/guix/mumi.git/tree/mumi/xapian.scm#n141
A search for "subject:foo" should work already.

Cheers!
Arun

Hi!

(I'll also try to retitle this bug, after submitting this update)

mumi advanced features could be **very** useful to a lot of contributing

activities, if improved a little bit and better understood

Uh I missed that code:

Toggle snippet (5 lines)

(index-text! term-generator subjects #:prefix "S")

otherwise I could have realize that I was misinterpreting mumi search

output.

If for example I search for 'subject:zoneinfo' I get this results:

Toggle snippet (10 lines)

giovanni@roquette [genv]\: mumi search subject:zoneinfo

#31484 [PATCH] gnu: icu4c: Patch zoneinfo directory.

opened on 17 mag 2018 14:58 by Christopher Baines

#57448 ? [PATCH 0/5] gnu: exa: Update to 0.10.1.

opened on 27 ago 2022 12:09 by ???

#58614 ? [PATCH 000/187] Remove unused crates

opened on 18 ott 2022 22:18 by Efraim Flashner

(the mumi CLI output is colored and the separation of each bug is

clearer)

Via web: https://issues.guix.gnu.org/search?query=subject%3Azoneinfo

Since 2 of the 3 patch "titles" are missing 'zoneinfo', I thought the

search was done in the subject and in the body, not just the subject.

For example, bug #58614 actually contains a message with this subject:

[PATCH 185/187] gnu: Remove rust-zoneinfo-compiled-0.4.

...my misunderstanding was due to the fact that each tracked bug (issue)

have a /Title/ given by the subject mail header from the original report

or by a retitle [1]; thus Title _is_ different from the "Subject"s of

the rest of the messages in the /thread/ of the tracked bug; when we

consider bugs tracking patches, actually each and every single patch

submission (not the reviews sent by people using a reply-to) do have a

different subject.

When searching for "subject:" it would be useful to have a speficic

message number and subject along with (or in place of) the bug title.

Using the search example above, a more useful result would be:

Toggle snippet (17 lines)

giovanni@roquette [genv]\: mumi search subject:zoneinfo

#31484 [PATCH] gnu: icu4c: Patch zoneinfo directory.

opened on 17 mag 2018 14:58 by Christopher Baines

#57448 ? [PATCH 0/5] gnu: exa: Update to 0.10.1.

opened on 27 ago 2022 12:09 by ???

[PATCH 4/5] gnu: rust-zoneinfo-compiled: Update to 0.5.1.

sent on 27 Aug 2022 12:10 by gyara

#58614 ? [PATCH 000/187] Remove unused crates

opened on 18 ott 2022 22:18 by Efraim Flashner

[PATCH 185/187] gnu: Remove rust-zoneinfo-compiled-0.4.

sent on 18 Oct 2022 22:20 by Efraim Flashner

I'd also add a blank line to have clear results also with "BW" consoles.

A similar addition would also be useful in the web interface, also

having a link to the message corresponding to the searched subject,

like:

[PATCH 185/187] gnu: Remove rust-zoneinfo-compiled-0.4. -> https://issues.guix.gnu.org/58614#184

Is it doable?

WDYT?

Thanks! Gio'

Hi Gio,

Sorry for my late reply. I have been travelling the last week and am

just catching up on all my email.

This is actually difficult to do because of the way we index issues as
Xapian "documents".

First, a quick Xapian primer. Xapian has a bunch of documents each
associated with a set of terms. When a search query comes in, Xapian
decomposes the query into a list of terms and retrieves documents that
match those terms.

In our case, we index entire issues as Xapian documents; we don't index
each individual email message as its own Xapian document. This means
that an issue is the smallest unit we can address. We cannot address
each individual email message. So, localizing a subject to a specific
email message is difficult.

Maybe what you are looking for is some context in the search results to
know why that particular search result was produced. This can be done by
displaying a snippet of text from the issue with the search terms
highlighted. For a working demo of what I mean, see for example,
https://issues.genenetwork.org/search?query=database&type=all. Notice
how the search term "database" is highlighted in the search
results. This is relatively easy to do with Xapian, and indeed I do plan
to implement this at some point.

WDYT? Would this meet your needs?

Regards,
Arun

Oooh: a live example is more than a thousand words: thanks!

OK: can we consider this bug report (wishlist) as the "official" one for

that feature? :-)

Can I retitle it to better reflect the upcoming implementation and

assign it to you?

Actually I dont' know if there is some written or unwritten convention

in Guix or GNU about bug assignment, I don't want to put pressure on

you!

> WDYT? Would this meet your needs?

Yes, absolutely yes: thank you!

Happy hacking! Gio'

As explained by Arun Isaac my feature request was not implementable, he

proposed a slightly different feature to give similar results.

Thanks!

No problem! I do intend to implement this feature at some point
anyway. Even if I don't do it, it's good to list this as an issue so
that someone interested can try and hack on it.
