The word "beer" is being stemmed to wrong synonyms

[runarbu]

The stemming for the word "beer" stemms it to unrelated synonyms "was", "is" and "are". Maybe "beer" is being stemmed to "be" and then extended again?

Somewhat relevant:
When searching for "phaser", searchd does not return results containing the word "phasers".

Example of document not found: http://perlcabal.org/syn/S04.html (has a Phasers heading)
