عند البحث في منتداي باستخدام tags:tag1
إذا كان tag1 مرادفًا لـ tag-one، فلن أحصل على أي نتائج ولن يتم عرض المنشور الذي يحتوي على tag-one.

أعتقد أن هذا السلوك غير مقصود على الأرجح ولذلك سأصنفه كخطأ.

حسنًا، ربما يجب علينا إضافة معالجة للمرادفات هنا، أوافق.

FIX: Resolve tag synonyms in search and filter queries (#37628)

What is the problem? Discourse allows admins to mark a tag as a synonym of anot…her tag. For example, "brunch" can be made a synonym of "lunch". When this happens, all topics tagged with "brunch" are automatically retagged with "lunch", and the `tags.target_tag_id` column on the synonym tag record is set to point to the target tag. However, several code paths did not account for synonyms: 1. **Search:** `Search#search_tags` and the hashtag advanced filter did not resolve synonyms. When a user searched using a synonym name (e.g. `tags:brunch`, `tags:brunch+eggs`, or `#brunch`), no results were returned because: - The `tags:` comma path queries `topic_tags` joined with `tags` by name, but topics are tagged with the target tag "lunch", not the synonym "brunch". - The `tags:` plus path aggregates tag names per topic into a tsvector and matches against the searched name, but the aggregated names are target tag names, so "brunch" never matches. - The `#` hashtag path picks the synonym tag's own `id` and queries `topic_tags` by that ID, but topics store the target tag's ID. 2. **Filter route:** `TopicsFilter#tag_ids_from_tag_names` concatenated both the synonym's own ID and the target tag ID. For match-all queries (e.g. `tag:brunch`), this required a topic to have both IDs in `topic_tags`, which never happens since only the target tag ID is stored. For negation queries (e.g. `-tag:brunch`), the exclusion targeted the synonym ID rather than the target, so no topics were excluded. What is the solution? In `Search#search_tags`, add a synonym resolution step before the existing comma/plus branching logic. It splits the match string into individual tag names, queries for any that are synonyms via `Tag.where_name(tag_names).where.not(target_tag_id: nil)`, builds a name mapping, and replaces synonym names with their target tag names. The replacement operates on the split array elements rather than using substring replacement to avoid corrupting tag names that may contain other tag names as substrings. In the hashtag advanced filter, pick both `:id` and `:target_tag_id` from the tag lookup and prefer `target_tag_id` when present, so the query uses the target tag's ID instead of the synonym's own ID. In `TopicsFilter#tag_ids_from_tag_names`, replace the transpose/concat approach with `.map { |id, target_id| target_id || id }` to resolve each tag to its canonical ID — the target for synonyms, or the tag's own ID otherwise. A partial index on `tags.target_tag_id` is added (scoped to `WHERE target_tag_id IS NOT NULL`) to support efficient synonym lookups.
