Google has a "verbatim" search filter, try. Try that together with quotation marks.
THeThe verbatim search filter shows up on a result "Pages Products Images Videos... Filter / All results".
Unfortunately, Google Search's "verbatim" option is not completely case-insensitive. Searching for "Cat" and "cat" will likely yield the same results.
Exceptions: There are situations where case sensitivity still plays a role:
Proper Nouns: Google might distinguish between proper nouns, even with the verbatim option. For example, a search for "Apple" (the company) might be different from "apple" (the fruit).
Acronyms: Verbatim searches on acronyms can be case-sensitive (e.g., "NASA" vs "nasa").
Programming Terms: Programming languages and syntax often rely on case sensitivity, so verbatim searches in this context might treat capitalization as important.
Use Quotation Marks: Enclosing your search terms in quotation marks ( "search phrase" ) gives you more precise control and usually ensures Google treats your query as case-sensitive.
