提高搜索速度性能的提示：搜索結果檢索？

Question

我使用search:search來檢索相當大的一組數據（0.5K到3K）來繪製一些圖表，並且還使用搜索API中的方面好處來允許最終用戶對數據集進行分面過濾，然後動態重建圖表。從數據庫中獲取數據並將數據提取到客戶端Web應用會花費大約5-10秒的時間（當數據集較小時減少），這對最終用戶來說並不令人愉快。我知道這是一個概念性問題，允許用戶輕鬆塑造被繪製的數據和這個過程的速度之間的平衡/妥協，但是，請大家非常感謝任何幫助/提示。謝謝！

PS：我使用search:parse，然後將查詢傳遞給cts:query嘗試提出了這樣的錯誤：[1.0-ml] XDMP-NONMIXEDCOMPLEXCONT: fn:data(<cts:and-query qtextjoin="AND" strength="20" qtextgroup="()" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:cts="http://marklogic.com/cts"><cts:element-range-query qtextpre="Jaar:" qtextref="cts:annotati...</cts:and-query>) -- Node has complex type with non-mixed complex content

Answer 1

您提到想要繪製圖表並創建構面。兩者都將基於價值而不是完整的文件。這聽起來像你可以返回，例如，10個文檔值，但從你的方面得到更大的列表。看起來您目前正在從提取元數據中獲取值。這是獲取某些信息以顯示個別搜索結果的好方法，但不是獲取有關數據集摘要信息的好方法。

您的約束條件都使用範圍索引，這很好 - 這些都會很快得到解決。對於您的圖表，您可能想要使用/ v1 /值來獲得同現值。

我想你的頁面長度更改爲10，並添加<小選項>上限= 100 < /小選項>到面，然後從面的，而不是提取元數據讓您的圖表值。此外，如果您可以安排索引以便unfiltered searches提供準確的結果，那麼您的搜索將運行得更快。

Answer 2

聽起來像你試圖抓住完整的搜索結果在一頁中（start = 1 page-length = 99999999）。您可能希望將策略更改爲以較小的批次（page-length = 100？）獲取結果，並且只是遍歷頁面，並動態地將越來越多的節點附加到圖表。一個好的圖表庫應該支持這一點。

HTH！
