我在solr配置中遇到错误.

我想创建一个应用程序来同步Tally Sales Order和Sales Invoice从Tally到我们的SQL数据库.目前我正在使用测试目的Tally ERP 9 Educational Version.

我已经创建了一些销售订单,并且需要所有订单以及来自计数器的详细信息 tally ODBC Sql query

uptil按照我的研究,我得到一些销售订单的细节,如Voucher Number,Order Date从符合ODBC表"凭证类型" ..等等CompanyVoucher.但很少有细节是空的,尽管相关数据按照统计顺序存在.像Reference,Party Name...等等.

此外,我无法找到Tally ODBC table其他几个与销售订单相关的数据等item name, item number , item quantity, rate and order total, order no.

任何人都可以建议SQL Query或Tally ODBC Table从哪里可以找到这些订单相关数据.此外,我不确定,如果我们无法访问这些细节Educational Version,以及访问这些细节的任何限制Educational Version.

所以请建议我这个.

我想myfield在solr中对字段应用不区分大小写的搜索.

我用Google搜索了一下,我发现,我需要应用LowerCaseFilterFactory字段类型和字段应该是solr.TextFeild.

我在我的应用程序中schema.xml重新索引数据,然后我的搜索似乎也区分大小写.

以下是我执行的搜索.

http://localhost:8080/solr/select?q=myfield:"cloud university"&hl=on&hl.snippets=99&hl.fl=myfield

以下是字段类型的定义

 <fieldType name="text_en_splitting" class="solr.TextField" positionIncrementGap="100" autoGeneratePhraseQueries="true">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <!-- in this example, we will only use synonyms at query time
        <filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
        -->
        <!-- Case insensitive stop word removal.
          add enablePositionIncrements=true in both the index and query
          analyzers to leave a 'gap' for more accurate phrase queries.
        -->
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords_en.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" …

我有一个表格接受Asp.net中的json帖子,我需要从Flash As3调用...

我正在使用下面的代码来做到这一点.我看过一些他们说工作正常的帖子.但我遇到下面的错误

Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.

这是我的代码.

        var messages:Array = new Array ();


        messages.push({"From":fromemailTxt.text,"To": ToemailTxt.text,"Body": BodyText.text,"Subject":SubjectText.text});

        var JsonObj:String = JSON.encode(messages);
        trace(JsonObj);

        var variables:URLVariables=new URLVariables(JsonObj);



        RequestURL= srvStringURL;

        var JSONLoader:URLLoader = new URLLoader();
        JSONLoader.dataFormat=URLLoaderDataFormat.TEXT;

        JSONLoader.addEventListener(IOErrorEvent.IO_ERROR, GetBookmarkURLError, false, 0, true);
        JSONLoader.addEventListener(Event.COMPLETE, parseBookmarkURLResult, false, 0, true);


        var hdr:URLRequestHeader = new URLRequestHeader("Content-type", "application/json");

        var request:URLRequest = new URLRequest(RequestURL);
        request.requestHeaders.push(hdr);
        request.data=variables;
        request.method = URLRequestMethod.POST;

        try 
        {
            JSONLoader.load(request);
        }
        catch (error:ArgumentError)

我在我的Solr中使用词干,但我并不总是想要为每次搜索应用词干.我想在一个特定的查询解析器上禁用词干,我可以这样做吗？

我需要一个正则表达式,它给我未封闭的标签,我可以找到它们并以编程方式关闭它们.

就像,我有下面的文字

<tag>
<p> hello world <p> this is <p>test.</p> this is test. <p> end it 
</tag>

我想从中找到未封闭的标签并使用Regex关闭它们.

任何的想法？？谢谢Meghana
