We have changed the way in which word stems are implemented on all the databases. The default algorithm was much too aggressive, resulting in many more matches often on irrelevant words, thus favouring Recall over Precision.
The stemmer now in use is much more conservative and should result in more accurate search results. This will also affect the relevancy scores – something Personal E-clips users will need to watch, as it could affect what threshold score is most effective.
This change is made as the result of precious feedback from our customers. Thank you.
