 # Search Media Items
 
-Search for media items by title, author, or description.
+Search for media items by title, author, series, tags, or contributors.
+
+**Note:** Search is case-insensitive and punctuation-agnostic. The search query is matched against normalized tags_search and contributors_search fields, allowing users to find matches regardless of casing or punctuation.
+
+Examples:
+- Search "acme corp" finds items with "ACME CORP." or "Acme Corp"
+- Search "oreilly" finds items with "O'Reilly Media" or "OReilly Media"
+- Search "science fiction" finds items with "Science-Fiction" or "science-fiction"
