Search Tips

To enter a query into our search engine, just type a few descriptive words and hit the 'enter' key. By default, queries concern the entire Caml Web site (, but the menu allows you to easily restrict your search to a specific subset of the site, such as:

Boolean Operators

You can use the boolean operators and, or, or not in queries. Without these boolean operators, the search engine will assume you're anding the words together. The operators are case insensitive. Evaluation takes place from left to right only, although you can use parentheses to force the order of evaluation. For instance

  (word1 or word2) and not word3 

retrieves entries containing either “word1” and not “word3” or “word2” and not “word3”.


A wildcard (*) is available. However, it can only be used at the end of a word. For instance, the query


only retrieves the entries which contain “doc”. On the other hand


retrieves all entries containing a word beginning with “doc”, e.g. “documentation”.


It is possible to form precise queries by using fields of entries: to limit a search to words found in a specific field, just prefix the keywords with the name of the field, followed by the equal sign. For instance,

  author=leroy or weis

retries all entries whose field author contains “leroy” or “weis”. Such queries can be combined using the boolean operators:

  (author=leroy or weis) and caml

The set of available fields depends on the corpus that is being explored:
