Hi,

we've built an index (Solr 4.3), which contains approx. 1 Million docs and
its size is around 20 GB (optimized).

In our index we have one field which contains the tokenized words of
indexed documents and a second field with the stemmed contents
(SnowballFilter, German2).

During our tests we've found out that some keywords are just taking too
long to process. When we exclude the stemmed field from our edismax
configuration (qf) the query time was surprisingly quick (10 000x faster).

Had one of you the same experience ?

We are using the stemmed field only to increase the returned documents and
not for highlighting. We know that by applying highlighting on stemmed
values is not good for query speed.

Best Regards,
Jens Meiners
