Changes

===Search is case-insensitive===

The searches for "fortran", "Fortran" and "FORTRAN" all return the same results.

<!-- ===Boolean search possible===

You can use the words "and", "or" and "not" and parentheses in order to

contain "Hitler" and either "Adolf" or "Adolph".

===Words with special characters===

In a search for a word with a [[w:diaeresis|diaeresis]], such as Sint Odili&euml;nberg, it depends whether this ë is stored as one character or as "&amp;euml;". In the first case one can simply search for Odilienberg (or Odili&euml;nberg); in the second case it can only be found by searching for Odili, euml and/or nberg. This is actually a bug that should be fixed -- the entities should be folded into their raw character equivalents so all searches on them are equivalent. See also [[Help:Special characters]].
