索爾索引與搜索

Question

任何人都可以建議我使用索爾的最佳方式，我的產品定期搜索，也應支持同義詞&模糊搜索嗎？

想，如果我有一句話CRO搜索，我需要的產品的任何地方開始結痂，然後痂出現在場上，然後同義詞&然後在其上的模糊在相應的提高

Answer 1

我有我的項目的情況。

我使用一起FuzzyLookupFactory（具有多個建議者）和AnalyzingInfixLookupFactory。我正在使用solrj（java api）進行請求查詢。

首先我搜索詞與analyzeinfixlookupfactory這可以找到字在字段中的任何地方，但你必須正確輸入。例如產品名稱「東芝」如果你搜索「胡說」它可以找到「東芝」正確，但是如果你搜索「TOSHBA」它不會找到任何產品。

這次我使用fuzzylookupfactory建議我拆分所有單詞（例如，你有「東芝筆記本電腦」word1 =東芝word2 =筆記本電腦等），並一對一搜索和模糊將找到TOSBA - >東芝，找到東芝後再次使用analyzeinfixlookupfactory查找完整的產品字段。

比如你要找到「東芝筆記本電腦」，然後搜索「TOSHBA laptp」。首先嚐試「analyzeinfixlookupfactory」並且響應將爲空。響應null搜索模糊每個單詞並添加你發現的東西像toshba - > toshiba + laptp-> laptop它將toshiba筆記本電腦，現在你可以再次搜索analyzeinfixlookupfactory完整的字段。
