TWiki::Query
A Query object is a representation of a query over the TWiki database.
Fields are given by name, and values by strings or numbers. Strings should always be surrounded by 'single-quotes'. Numbers can be signed integers or decimals. Single quotes in values may be escaped using backslash (\).
See QuerySearch for details of the query language. At the time of writing only a subset of the entire query language is supported, for use in searching.
A query object implements the evaluate
method as its general
contract with the rest of the world. This method does a "hard work" evaluation
of the parser tree. Of course, smarter Store implementations should be
able to do it better....
