Wrong search results

[apicedda]

Hello there, not sure if it's the right section to write on. This forum is showing completely messed up on my side, like not loading css. Anyway

 

The issue is: the results when performing a search on my prestashop site are just wrong. Like if i search the brand Nike it shows results about Adidas. I tried changing the search weight and rebuilding the index but nothing has changed. Any idea on how to debug this?

 

Thanks

I think i found what could be wrong, the search is giving priority to the full description even though i set the max weight to the title>category>brand>description . Any idea on how to fix it?

I wouln't index the products full description. It blows up the related database tables and usually it results in less precise search results. So I recommend to always set full description to zero.

setting full description index weight to 0 solves the issue but setting it 1 or higher makes the results count it as highest weight even though the highest is title. So if anyone knows what to look for to try fixing this let me know. Thank you Scully for the tip

I haven't tested this with weight 1. Sounds like a bug. However my strong opinion remains that full text isn't a good index. Our customers have quite long texts with a lot of details they don't want to be searched in.
