Task Breakdown notes:

• The results of the pre-configured list of lexical categories always appears before the results from the API
• Ensure that the boosting remains effective for different interface languages
• Are lexical categories filtered against the search results in the same way that the spelling variants are filtered (i.e. there's a word starting with the search term, in the name)? @Lydia_Pintscher

Potential plan of action:

1. Create a config for item IDs
2. In the server side we can get their labels
3. Get item IDs and labels to the client side (RL or otherwise)
4. Once the list is in the client we can filter out this list against the results, prepend the results list with the boosted items and de-dupe the list.
5. Add configuration for Beta Wikidata so that the task can be verified.

I'd say it should behave the same way with the lexical categories prioritized as without. So that'd be matching on the start of words.

Hm, but the search results might include one of the suggested/prioritized lexical categories even when we didn’t match it without the search API (e.g. it matches an alias while we only check labels, or it matches in another language). What happens in that case?

For example: suppose I search for “supin”, in English. The wbsearchentities result (currently) starts with two items: supine, “a noun-like verb form used in various languages” (i.e. actually a grammatical feature rather than a lexical category, but ignore that for the moment), and verb, which has the alias “supin” in Romanian. Should we show “verb” above “supine”, because the former is one of the suggested lexical categories while the latter isn’t, even though without the API we wouldn’t have any connection between the search term “supin” and the item “verb”?

(Actually… what’s the order of the suggested lexical categories anyways, i.e. in what order do we show the matching items after filtering? The same as the order in the full list from the config?)

We discussed this in a call – as long as the items are included in the results somewhere, the exact position isn’t important. We’ll see what is easiest in the code.

This is live on Beta with three lexical categories: noun, adjective, adverb.

Moving back to doing because I noticed we’re including the suggested items in the search offset, meaning some search results get skipped.

This was fixed as part of the work on T308118 (specifically #184), the task should be good to review again.
