Umbraco 检查搜索查询空值

Question

我正在尝试修复我的搜索引擎。问题是当我搜索我现有的博客项目时，它总是说

Did not match in any document

无论我搜索什么，它总是给我错误信息。

有什么办法可以解决这个问题还是我的代码有问题？

@using Examine.LuceneEngine.SearchCriteria
@inherits Umbraco.Web.Macros.PartialViewMacroPage

string searchTerm = Request.QueryString["search"];
var searcher = ExamineManager.Instance.SearchProviderCollection["MySiteSearcher"];
var searchCriteria = searcher.CreateSearchCriteria();
var query = searchCriteria.Field("nodeName", searchTerm).Or().Field("bodyText", searchTerm).Compile();
var searchResults = searcher.Search(query);

@if (searchResults.Any()){
    <ul class="search-results">
        @foreach (var result in searchResults)
        {
            IPublishedContent node = Umbraco.Content(result.Fields["id"]);
            <li>
                <a href="@umbraco.library.NiceUrl(result.Id)">
                    @if (result.Fields.ContainsKey("nodeName")) {
                        @node.GetPropertyValue("blogItemTitle")
                    }
                </a>
                <p>@result.Fields["blogbodyText"]</p>
            </li>
        }
    </ul>
} else {
    <p class="error-result">
        Your search
        @if (!String.IsNullOrEmpty(searchTerm))
        {
            <strong><text>'@searchTerm'</text></strong>
        }
        did not match any documents.
    </p>
}

这是我的设置

Answer 1

需要检查几件事，首先，检查您的索引是否实际填充正确。您可以从here 下载工具 Luke（需要 Java）。这个方便的工具可让您查看索引的内容。

如果您启动 Luke 并将其指向 /App_Data/TEMP/ExamineIndexes/MySiteSearcher 中的索引文件夹，它应该会显示索引器中有多少项目以及它们包含哪些字段。检查 a) 索引中有文档，b) 索引正在索引您正在搜索的字段。

如果一切正常，则可能是搜索的语法。查看您的代码，您最终会得到要求 nodeName 与搜索词匹配的搜索，在 bodyText 中有一个可选匹配（默认搜索运算符是 AND，这意味着查询中的第一项必须始终匹配）。如果您想匹配其中任何一个，您需要将搜索的默认运算符设置为 or，使用以下代码：

var searchCriteria = searcher.CreateSearchCriteria(Examine.SearchCriteria.BooleanOperation.Or);
