A topic name can contain up to 128 alphanumeric characters, including hyphens and underscores.
Topic names and evidence topics are normally case-insensitive. You can name a evidence topic using all caps, as in APPLE, initial caps, as in Apple, or all lower-case, as in apple. Case is not considered when a search is performed. Thus, if your evidence topic is entered as APPLE, the Verity search engine selects documents containing “APPLE”, “Apple”, or “apple”.
You can, however, use the CASE modifier to specify that case match the entry of a evidence topic.
