The colon character has a special meaning in searches, telling the search engine what field to search in. For example, author:jones. In most other cases, you should leave colons out of your search. If they are necessary to your search, add a backslash in front of them so we know how to search them. For example, id:alpha\:theses\:1234.
The slash character (/) can be included in searches only if it is included in quotes ("over/under") or has a backslash in front of it (id:alpha\:theses\/5678). In most searches, slashes can be safely left out.
