I am able to search for " Svanenmärkt" , “ISOTECH Toner CE410X 305X Svart Hög Kapacitet” etc…
I have tried several other products with the extra character “Ö Ä Å ä å ö” an it works.
When it comes to Miljötoner it does not work.
I have tried to change it to
Miljätoner (Not working)
Miljåtoner (Not working)
Miljotoner (Working)
I assume this has something to do with the combination, Lucene indexes it as a diffrent word.
Looking forward to inputs and suggestions.
Have you done any modifications of the ProductSearchService?
Is it searching in the body tag?
Can you reproduce it locally and inspect the index to see that the data is there?
I’ve tested this in 7.5.0 using an Editor field and I get responses back for Miljötoner.
