The
VectorStoreChatMemoryAdvisordid not support setting a similarity threshold, so it was fetching everything it found including messages that were not relevant to the user's message in the case where the user has asked about a different topic.I experimented with setting a threshold higher than 0 and liked the results so I thought I'd submit a PR. The default is still 0 so as not to change the original behavior.
