Hossman, thank you for clearing that up. The reason I create a new searcher
for every search is that the index is frequently updated, and as far as I
could read the documentation, a searcher will not detect changes in the
index that occured after it was opened. I tried using just one searcher, but
that did not work. As for the rest of the code, SolrJ is not available until
Solr 1.3, and I actually never found the example provided at
http://wiki.apache.org/solr/EmbeddedSolr (I can't see that it's linked to
from the main wiki), I only found this http://wiki.apache.org/solr/SolJava.
Anyway, I'll see if I can convert my code to the logic of the example at
EmbeddedSolr.
