Problems with SEARCH BAR Prestashop 8.2.1

[BeginnerPrestash 8]

hello, everyone,

I am having problems with  SEARCH BAR.

These are the problems I'm having.

1. When I enter a product reference it does not appear in the search results.

2. When any word gives me results that do not have any match with the results.

3. When I enter a reference of more than 7 digits, no results appear.

4. If the reference is letters and numbers, no results appear.

I have tried to solve it from Store Parameters - Search but the changes are not applied correctly.

I attach photos of the Front.

Best Regards

these usually come down to indexing + weights + tokenization.

make sure “reference” is weighted and reindex

o go to shop parameters → search
o in weight, set reference > 0 (10 is a good start)
o enable indexing (auto-index on save)
o click re-build entire index — if still bad, truncate ps_search_index + ps_search_word (backup first!) and rebuild

tune tokenization settings

o check minimum word length (try 2)
o review blacklisted words
o if theme/module offers “search within word” or “exact end match,” enable it

understand what gets indexed

o core search indexes product main reference, not each combination’s reference
o if you rely on combination references, place them in short description or use a module that indexes them
o note that older limits on word length may still drop long numeric tokens; lowering minimum word length + reindexing helps

known 8.2.1 issue

o edited products sometimes aren’t re-indexed; rebuild and be sure indexing = enabled

extra tips for numeric / alphanumeric refs

o numeric-only queries act differently; low min length + rebuild usually fixes
o for alphanumeric refs (ex. AB12345), test via /search?controller=search&s=AB12345 to bypass any theme JS filtering
