Based on what I have read, it looks like only a collection reload is needed for the scenario below and for that matter for applying any modifications to the solrconfig.xml.

In this release we will be moving from an AutoSuggest feature based on the Suggestor component to one based on an Ngram approach. We will perform a re-index of the source data. [<https://lucidworks.slack.com/archives/iss/p1458744017000058> After updating the Solr config for each collection a collection reload (via the Solr collection api) will be executed. My question is whether this reload will clear the memory used by the Suggestor component or if a Solr restart on each Solr node will be necessary to clear the in-memory structure that was previously used by the Suggestor component. Thanks, Matt
