+/// Exact term/phrase matching function for text columns.
+///
+/// This function checks if a text column contains exact term/phrase matches
+/// with non-alphanumeric boundaries. Designed for:
+/// - Whole-word matching (e.g. "cat" in "cat!" but not in "category")
+/// - Phrase matching (e.g. "hello world" in "note:hello world!")
+///
+/// # Signature
+/// `matches_term(text: String, term: String) -> Boolean`
+///
+/// # Arguments
+/// * `text` - String column to search
+/// * `term` - Search term/phrase
+///
+/// # Returns
+/// BooleanVector where each element indicates if the corresponding text
+/// contains an exact match of the term, following these rules:
+/// 1. Exact substring match found (case-sensitive)
+/// 2. Match boundaries are either:
+///    - Start/end of text
+///    - Any non-alphanumeric character (including spaces, hyphens, punctuation, etc.)
+///
+/// # Examples
+/// ```
+/// -- SQL examples --
+/// -- Match phrase with space --
+/// SELECT matches_term(column, 'hello world') FROM table;
+/// -- Text: "warning:hello world!" => true
+/// -- Text: "hello-world"          => false (hyphen instead of space)
+/// -- Text: "hello world2023"      => false (ending with numbers)
+///
+/// -- Match multiple words with boundaries --
+/// SELECT matches_term(column, 'critical error') FROM logs;
+/// -- Match in: "ERROR:critical error!"
+/// -- No match: "critical_errors"
+///
+/// -- Empty string handling --
+/// SELECT matches_term(column, '') FROM table;
+/// -- Text: "" => true
+/// -- Text: "any" => false
+///
+/// -- Case sensitivity --
+/// SELECT matches_term(column, 'Cat') FROM table;
+/// -- Text: "Cat" => true
+/// -- Text: "cat" => false
