Hello,
We have been using the same code for many months to search for products in our catalog. Recently though we started having issues where the same search query would produce different results. Sometimes the results are correct, but a lot of the time they are wrong as the results do not include products that should be there. This happens both through our production and dev indexes. I went through our code and setup some tests and found out that FilterForVisitor() was causing the issues. Once I took that out, the results became consistent, but we need this because, as I have read, it filters out unpublished products.
I am not sure what might have changed in our environments to cause FilterForVisitor() to stop working, but any guidance would be highly appreaciated.
Thanks
