Makes sense. I'll look into how to get those. Is language code OK or we
need full language name (uk vs. Ukrainian)?

One thing to note here is that secondary languages have no order - i.e.
if you look in German, and there's no matching German label, but there
are 10 other language labels all the same (happens a lot for names &
places), which language will be selected is anybody's guess. We could
add rule that says "look at English as secondary first", in theory, but
not sure whether we should - after all, besides having most languages,
(and us speaking it :) there's not much special about it.

OK.

OK, I'll try to make this.

OK then, I'll feel free to shuffle things around then :) Having more
freedom in the title line is good because we can then display both label
& aliases.

When showing labels from fallback languages we do have little language
indicators in other places. I believe we should have this here as
well. Otherwise I believe it is confusing where certain labels
suddenly come from because you might not see them when going to the
actual item.

I'm slightly leaning toward showing both.

It helps in the cases where you want to get an understanding about how
large an item is and if it is worth your attention. If people actually
use it... Not sure. They definitely do in recent changes and history.

I'd say in this case we could get rid of the word/byte count. To get a
good glimpse of the quality of the item I'd say we'd want to show
count of statements (excluding identifier statements), identifiers and
sitelinks.

Not sure if we had a reason tbh.

We have the code to index statements already, and we're already indexing
P31 and P279. We could index more properties. We don't have syntax or
any other way though to actually use those in search - yet, except for
boosting (see https://gerrit.wikimedia.org/r/#/c/384632/).

We're looking at which properties to add (nominations welcome, probably
in the form of phab ticket?) - since adding them requires full reindex
of wikidata (couple of days) we probably don't want to add them one by
one but want to collect a set and then do it in one hit.

We also do not have syntax for searching (as in match, instead of boost)
by statement values, but it should not be hard - we just need to design
proper syntax and implement it (syntaxes are now pluggable, so should
not be too big of a problem).

Hi Stas,

while you are at it, some things would be very useful to be search-able
(maybe some are already by now):
* "primary" (not references/qualifiers) years, for birth/death/flourit etc.
* "primary" string/monolingual values (title, taxon name, etc.)
* "primary" IDs, e.g. VIAF (might cause confusion with years, so maybe only
add numerical IDs if 5+ digits?)

Cheers,
Magnus

[Wikidata-tech] Wikidata fulltext search results output

[Stas Malyshev]

Hi!

As I am working on improving Wikidata fulltext search[1], I'd like to
talk about search results page. Right now search results page for
Wikidata is less than ideal, here are the issues I see with it:

- No match highlighting
- Meaningless data, like word count (anybody cares to guess what it is
counting? Anybody ever used it?) and byte count (more useful than word
count but not by much)
- Obviously, search quality is not super high, but that should be
improved with proper description indexing

While working on improving the situation, I would like to solicit
opinions on the set of questions about how the search results page
should look like. Namely:

1. If the match is made on label/description that does not match current
display language, we could opt for:
a) Displaying the description that matched, highlighted. Optionally
maybe display the language of the match (in display language?)
b) Displaying the description in display language, un-highlighted.
Which option is preferable?

2. What we do if the match is on alias? Do we display matching alias,
original label or both? The question above also applies if the match is
on other language alias.

3. It looks clear to me that words count is useless. Is byte count
useful and does it need to be kept?

4. Do we want to display any other parameters of the entity? E.g. we
have in the index: statement_count, sitelink_count, label_count,
incoming_links, etc. Do we want to display any?

5. Display format for Wikidata and for other wikipedia sites is different:
Wikpedia:

Title
Snippet

Wikidata:

Title: Description

I.e. Wikipedia puts title on a separate line, while Wikidata keeps it on
the same line, separated by colon. Is there any reason for this
difference? Do we want to go back to the common format?

Also if you have any other things/ideas/comments about how fulltext
search output for wikidata should be, please tell me.

I am sending this to wikidata-tech and discovery team list only for now,
since it's still work in progress and half-baked, we could open this for
wider discussion later if necessary.
