Search issue

When I write some word to look for in the search bar, like “NY” I get different results of searching:

–Some posts of the web because appear the word “ANY“, so the searching mode don´t discriminate the full word. For this first search, is it possible to set the whole word?, I mean, not letters contain in another word.

-Another search is the contact page, where it shows a long chain of words, I have checked it, and I don´t find any “NY” in it, first of all, it shows as an error in the window because it fills the sidebar gap, and also the error of a wrong search without the term “NY”. ¿Why does it happen? ¿How can avoid it?

-The last searchs are empty templates that I downloaded to do tests, but is the original contain (no modify), as you can see, they also appear in the search, and also they don´t have any “NY” in it, ¿Why does it happen?

Thanks

Hi Calin, now I´m using xampp in my computer to emulate the web, so I have to wait some days to upload on the internet. But I have to say you that I use the last theme version and only plugins available for your support (Yoast SEO, Slider revolution, Contact Form , AMP and Akismet Anti-Spam).

Thanks
