In my shop I've got product with name for example: VANS AUTHENTIC LITE Z5J187 and when I'm searching for vans or authentic or lite I've the results. But when I'm trying to search for Z5J187 I'm getting no results.
I've figured it out that in the database there's a table ps_search_word with words that are used for search. I've noticed that there are words like: vans, authentic etc. but not Z5J187 and any other code like this.
In Search.php class file there are declared variables like PREG_CLASS_SEARCH_EXCLUDE, PREG_CLASS_NUMBERS, PREG_CLASS_PUNCTUATION. When I've cleared the PREG_CLASS_NUMBERS and Re-build the entire index in the table ps_search_word there are new words and there was some of the products codes but not all, but also there was no vans, nike etc. words.
What should I change so the idexation puts also my product codes into table ps_search_word?
I didn't see this problem on prestashop.
on this website :
serch these words:
PTT201
520DS
My guess is this:
You probably changed the product name after indexing
Solution:
on BO, goto Preferences>>search and reindex all
