If I enter, let's say 'NYC', then the description will appear correctly for the post in which there was a googletagmanager if you enter 'ny' - Correct search
As I understand the search is looking for a complete match of "NY" in the article and does not find it therefore returns googletagmanager. But 'NYC' is looking for it correctly, so this word is completely in the article.
Please tell me what you can do to prevent 'googletagmanager' from displaying.
