Help for Broker Queries

This Broker handles several types of queries.

The simplest query is a single word, such as:
Ex.: Author: mustermann

Also
Ex.: Author: karl mustermann
works as expected.

Search is case insensitive.

Matches on word boundaries
Ex.: Author: muster
will also be displayed.

Umlauts: ä = ae ; ö = oe ; ü = ue ; ß = ss
Ex.: Author: mustermaennchen
will also search the papers of "Mustermännchen".

Boolean queries are supported.
'AND' and 'OR' have to be in capitals.
Boolean expressions must have proper bracketing '(' ')'.

feature: The broker currently is ignorant about the rule: 'AND' precedes 'OR'.The brackets
Ex.: Title: (dog AND cat) OR potatoe
cannot be omitted.

Wild cards: '.' matches one character and '#' matches one or more characters:
Ex.: Title: comp.ler AND com#ter

There are settings for

approximate matches (e.g., allowing spelling errors) and
limitation on the number of objects returned

At the beginning of the result set the translation of a query to a search string is displayed.

Those familiar (with the way Harvest remodels) the full query syntax of the underlying glimpse database, may want to use the first entry of the query interface labelled 'text'.
