Subject Re: lucene 2.9.0RC4 slower than 2.4.1?
Date Wed, 16 Sep 2009 16:55:50 GMT
So here's a debug message showing the query:

2009-09-16 18:53:59,642 [DEBUG] [http-8440-2] [] [2144122] []
service.impl.LuceneBaseService: items search('viewable:(FINDALL 0 1 2 )',
BooleanFilter( +CachingWrapperFilter(QueryWrapperFilter(+issalesallo
wed:true)) +CachingWrapperFilter(QueryWrapperFilter(licenseGroupKeys:lablxrox))
+CachingWrapperFilter(QueryWrapperFilter(+(viewable:1 viewable:2)))
oryIds:146)) +CachingWrapperFilter(QueryWrapperFilter(+contentGroupIds:14554))
-CachingWrapperFilter(QueryWrapperFilter(digitalReleaseDate:{lablxrox20090916 TO
lablxrox99999999} digitalDeleteDate:[lablxro
x19000101 TO lablxrox20090916]))
<custom:"position": null>, 0,

By the way, will it make sense to move this into a jira issue? It'll get quite
tough to find the right information already since this thread is growing quite fast.
