Case sensitive searches ARE very important

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.
