The need to search text and pdf files for acronyms is essential. The problem is, many acronyms are normal words when case sensitivity is eliminated.
I do healthcare research.
Today, for example, I need to identify all PDFs which mention the CHOIR treatment study. The problem is the search also pulled up documents that also reference a singing or church choir. That is a big problem for me. I must retrieve info today on the TREAT, CHOIR and CREATE treatment studies. Without case sensitivity I cannot do so reliably.
Yes, case sensitivity is very important for searching.
