Language Detection Riak Search

Hello again everyone,

Since I am using Java, I ended up going with a solution where I just used
the langdetect library right in my Java code and simply appended the
language code to the strings I want to be able to search. I've found it's
actually much easier than configuring the update request handlers since I
can test and see what's going on with my code much more easily. I'm not
sure what the appetite is for others but I won't be needing the extracting
request handlers feature.

After enabling this, however, I began to get bad performance, in the range
of over 1 minute for insertions. I am assuming this is a Solr issue since
the performance issues only occur on documents that are indexed and which
are being matched to dynamic language fields. Has anyone seen similar
performance issues when mapping language specific fields?
