If you search for it in the search box without the apostrophe, then the article doesn't come up as a result. In casual typing people quite often omit the apostrophe, so this is a practical problem. Sandomierz is just an example - there are many more article titles with an apostrophe in Hebrew and in some other languages.
It's just a simple and common punctuation mark, so the search engine should be smart enough to find the article.
This is comparable to T75862, but it should be much simpler, because this is just about punctuation and not morphology.
