Hi all, I know the suggester component will work on distributed indexes. It works fine when I'm only using the suggester component in the components chain, but I'd like to apply the suggester to the end of the default components chain (query, facet, mlt, etc..). When I do, I get an error. For example, if I add:
<arr name="last-components"> <str>suggest</str> </arr> at the end of the default "/select" handler, the error I see is: http://localhost:8983/solr/suggest-test/select?q=obie { "responseHeader": { "zkConnected": true, "status": 500, "QTime": 63, "params": { "q": "obie" } }, "error": { "trace": "java.lang.NullPointerException\n\tat
