The WinMX client enables searches to be improved by using - and ~ operators to refine search results.
The - (minus) operator can be used to exclude results,
and the ~ (tilde) used to replace/substitute words/characters.
The - command example
top search box contains: radiohead live
bottom contains : -berlin -nijmegen
top search box contains: -berlin -nijmegen radiohead live
These examples would return results containing the words 'radiohead' and 'live',
whilst excluding results containing the words 'berlin' and/or 'nijmegen'.
Note: The negated words need to be entered into either the lower type field,
or be placed before the words to be included.
For example, the following does not work...
top search box contains: radiohead live -berlin -nijmegen
The ~ example
top search box contains: radiohead ~sub
top search box contains : radiohead
bottom contains : ~terr
These examples would return results containing 'radiohead',
and additional words containing either 'sub' or 'terr', e.g. Radiohead & Subterranean.
Combined ~ and - examples
You can use both operators at the same time if you like...
top search box : radiohead live
bottom : ~sub -berlin -nijmegen
top search box : -berlin -nijmegen radiohead live ~sub
These examples would return anything containing the words 'radiohead' and 'live',
and also containing 'sub' as any part of a word,
whilst negating 'berlin' and 'nijmegen' from the displayed results.
