I wrote it for the jollies of it. About the search engine. All words, with the exception of short and some common words, are indexed by a highly optimized gdbm-based indexer. Partial word searches are not implemented, and all searches are case insensitive and strictly alphanumeric. Searches are parsed using a right associative parser that generates lists of articles from the index.
Parse errors are more or less ignored.
About Entring Posts. Posts are indexed and stored in a linear database. A maintenance program should one day delete old posts after a fixed period of time or when they have been deleted. About Deleting Posts. Currently, posts are not deleted exactly, because it is not completely clear how to refer to branches of the tree that have been cut off due to the deletion.
