+
+Detects and counts occurrences of multiple keywords in the text in different case variations (lowercase, uppercase first letter, or all uppercase).
+
+# Arguments
+- `keywords::AbstractVector{String}` Vector of keywords to search for
+- `text::String` The text to search in
+
+# Keyword Arguments
+- `mode::Union{String, Nothing}` When set to "individual", only counts matches that are individual words (default: nothing)
+- `delimiter::AbstractVector` Characters used to determine word boundaries when mode="individual" (default: [' ', '\n', '.'])
+
+# Returns
+- `Dict{String, Integer}` Returns a dictionary mapping each keyword to its count in the text (0 if not found)
