Context / Scenario
When calling MemoryWebClient.SearchSummariesAsync with PipelineOnlySummary, the value of results[0].partitions[0].relevance in the answer object becomes -Infinity.
The relevance value is: -1.7976931348623157E+308

Tony：好，那我們今天就針對大學面試要注意的事項來聊一下，看看大家有沒有什麼經驗或建議可以分享。
Cindy：好啊。我覺得第一個重點是要做功課，像是去查該系的課程、教授的研究方向、還有該科系重視的特質。
RM：嗯，沒錯。面試老師常常會問「你為什麼想讀我們這個科系？」這種問題，如果回答太空泛就不太加分。
Tony：對，我記得以前有人就說「因為分數剛好到這裡」，這種就...有點糟糕（笑）。
Cindy：哈哈，對。還有服裝儀容我覺得也不能忽略，乾淨整齊、得體就好，不用太正式，但一定要讓人覺得你是有準備、尊重這場面試的。
RM：那說到面試技巧，我會建議大家可以事先練習幾個常見的問題，比如「你的興趣是什麼？」、「你怎麼看待團隊合作？」之類的，甚至找朋友模擬一下會更有幫助。
Tony：對，還有自我介紹最好控制在一分鐘內，而且要有重點，不是從小講到大（笑）。
Cindy：哈哈沒錯。另外，如果有參加過比賽或專題，可以稍微提一下，重點是要跟申請的科系連結起來，才有說服力。
RM：最後我覺得也很重要的是要有禮貌，進出面試場都要記得打招呼、感謝，這些小細節其實老師都會注意到。
Tony：總結一下，大概就是：事前準備、儀容得體、自我介紹有重點、練習常見題、還有基本禮儀。這樣應該就能讓印象加分不少。
Cindy：嗯嗯，我覺得這樣一份小提醒給學生也很有幫助。
RM：沒錯，那我們就整理一下今天的重點，看看能不能做成一張 checklist 給學生參考。
Tony：好，今天的討論先到這邊，感謝大家！

- Should we add a check for
if (recordRelevance < float.MinValue)in the ProcessMemoryRecord method?
if (result.Mode == SearchMode.SearchMode)
{
// Relevance is `float.MinValue` when search uses only filters
if (recordRelevance > float.MinValue) { this._log.LogTrace("Adding result with relevance {0}", recordRelevance); }
