PDP-8 Document Search Help
This search uses the syntax used by many of the web search engines. Documents which match any of the words will be shown. For this search only the document number, title, and keywords are searched. The text of the documents is not searched.

  "maintenance manual" -pdp +disk

Three search types are available

Words are considered only letters so the word User's is considered two words User and s for comparison. If you enter a word such as User's it will match User's as expected. Currently Users will not match User's.

Since there aren't that many documents use the shortest search and don't use plural words to try to avoid missing documents.
