Are Queries Case-Sensitive?

The Coveo Platform 7 queries are not case-sensitive as you cannot find only the documents containing a specific casing variant of a term.

However, the unified index records which documents contain casing variants of terms (first, all, or some letters in uppercase). When you search for a specific casing variant of a term, the search results include all casing variants of the searched term, but the results containing the casing variant you are searching for are ranked higher (see Understanding Search Results Ranking).

Tip: Because by default queries are expanded using stemming, returned documents also include related terms sharing the same root (see About Stemming). To reduce the number of results, you can however disable the stemming expansion using the exact term prefix (+) in front of your casing variant term (see Searching an Exact Term) so that the search results only return documents containing casing variants of the term, not those containing the other terms sharing the same stem.
