How to make Sphinx search work with slash character?

Question

Sphinx

Hello!
How can I configure sphinx to search in that given the slash "/"?
After all the settings, the search works almost perfectly, but there are times when, for example, we are looking for products that have a slash in the article, for example, we enter 1155, then it will find all products where there are such numbers in the article, if we enter "1155/", then items with SKUs like "1155/A", "1155/B", etc. does not search until we add a letter. I tried to replace, for example, a slash with a dash before searching, then it looks for such options, but plus others, such as "1155-54", etc., but I need to search only where "1155 /" is completely found.
Tell. please.
Thank you!
