Search modes

  • "Default" — This follows the xapian search syntax. Note that phrase and NEAR search needs the positional information when indexing. The positional information will make the xapian index file too big. The program has used a balanced way to enable or disable the positional information automatically based on the total document length.which means the positional information will not be disabled when the ditionary has reached the limit.
  • "Plain text" - mode like "Whole words" but every word in search line can be treated as word fragment.
  • "Wildcards" - the search line contains a Unix-like template. Such template can contain wildcard symbols ? (matches any one character), * (matches any character number) or ranges of characters [...] To find characters ?, *, [ and ] it should be escaped by backslash like \?, \*, \[, \].

"Available dictionaries in group" - here you can view how many dictionaries in the current group are suitable for full-text search, how many dictionaries already indexed and how many dictionaries wait for indexing.

When you place mouse cursor over headword in results list, the tooltip with dictionary list contains such articles matched the search conditions will be shown.

!!! note The dictionary will index for full-text search in background and started immediately after program start, name of the currently indexing dictionary is displayed in the status line. This process can take a long time and require many computing resources.You may turn off indexing for huge dictionaries like Wikipedias or Wiktionaries in preferences. To find dictionary which can't be indexed check GoldenDict with --log-to-file or check stdout.
