Search for Related Categories limited to 10 display

[julos0877]

Hello,

When I'm creating a new product, in the product detail page, custom field tab, I want to choose my related categories but the search engine propose me only 10 categories maximum.
The problem is that I have more of 10 categories with the same word in the title.

Here I want to select the category sound effect but I have lot of categories with sound effect in the title such as Forest sound effect or Rain sound effect. So 10 categories are showing in the search result but no more and the category I want is not displaying.

Do we have the possibility to increase the number of the diplsayed categories in the search to see all the categories with the word in the title.

Thanks in advance
