Improve the performance of server-based translation memory (TM) searches (on the selected TM) with the tools available in the Performance and Tuning page of the Translation Memory Settings dialog.

OptionDescription

Fuzzy Index Statistics

Fuzzy index statistics are used during fuzzy searching. They can improve the speed of the search, particularly in larger TMs (a TM containing less than 50,000 translation units is considered to be small). You should update the fuzzy statistics after performing a large data import.

You will get a notice in this section to recompute the fuzzy statistics when Trados Studio detects that a TM containing more than 50,000 translation units (TUs) has grown with more than 10% in size. If that happens, or if you notice that searches are becoming slow, update the fuzzy statistics.

  • Statistics last updated on - This is the date the statistics were last updated.
  • Translation units added since - This is the number of TUs added since the last update.
  • Recompute Fuzzy Index Statistics - Select this option to update the fuzzy statistics.

Fuzzy Index

You should re-index the TM when you update the Recognize settings (for example, the Recognize dates or Recognize numbers options) used in the TM. If you do not update the fuzzy index, the new 'recognize' items will not be indexed.

Advanced Tuning

This option enables you to improve the speed of TM searches. However, the speed is achieved at the expense of accuracy.

Dragging the slider to the right improves the speed at which results are retrieved, but it does this by excluding TUs that would ordinarily have been included in the results. The further you drag the slider to the right, the more TUs are excluded.

TUs are excluded on the basis of their match percentage. As you drag the slider to the right, the fuzzy match threshold for the search is raised and the lowest matching TUs are excluded from the results. The further you drag the slider to the right, the higher the threshold becomes.
