The documents in a result list are normally sorted in order of relevance. It is possible to specify different sort parameters by using the Sort parameters dialog (located in the Tools menu).
The tool sorts a specified number of the most relevant documents in the result list, according to specified criteria. The currently available criteria are date and mime type.
The sort parameters stay in effect until they are explicitly reset, or the program exits. An activated sort is indicated in the result list header.
Sort parameters are remembered between program invocations, but result sorting is normally always inactive when the program starts. It is possible to keep the sorting activation state between program invocations by checking the Remember sort activation state option in the preferences.
It is also possible to hide duplicate entries inside the result list (documents with the exact same contents as the displayed one). The test of identity is based on an MD5 hash of the document container, not only of the text contents (so that ie, a text document with an image added will not be a duplicate of the text only). Duplicates hiding is controlled by an entry in the Query configuration dialog, and is off by default.
