Need help with this one, really struggling to get it working.

OK i've got a site with articles. I want to allow the user to search by keyword and phrase so:

searching for How would pull back articles with How in the title, body etc

searching for How To would also pull back articles with How To in the title, body etc

Sooooo to this end i've setup the following:

ExamineIndex.config:

<ExamineLuceneIndexSets>

  <IndexSet SetName="KBIndexSet"

             IndexPath="~/App_Data/ExamineIndexes/KBSearcher/"

             IndexParentId="1640">

    <IndexAttributeFields>

      <add Name="id" EnableSorting="true" Type="Number" />

      <add Name="nodeName" EnableSorting="true" />

      <add Name="updateDate" EnableSorting="true" Type="DateTime" />

      <add Name="createDate" EnableSorting="true" Type="DateTime" />

      <add Name="writerName" />

      <add Name="loginName" />

      <add Name="email" />

      <add Name="nodeTypeAlias" />

      <add Name="updateDate" />

      <add Name="createDate" />

      <add Name="pageID" />

    </IndexAttributeFields>

    <IndexUserFields>

      <add Name="pageTitle" />

      <add Name="bodyText" />

      <add Name="search" />

      <add Name="articleTitle" />

      <add Name="articleType" />

      <add Name="product" />

      <add Name="category" />

      <add Name="symptoms" />

      <add Name="purpose" />

      <add Name="resolution" />

      <add Name="additionalinformation" />

      <add Name="keywordsToSearchUpon" />

    </IndexUserFields>

    <IncludeNodeTypes/>

    <ExcludeNodeTypes />

  </IndexSet>

 

    <!-- The internal index set used by Umbraco back-office - DO NOT REMOVE -->

    <IndexSet SetName="InternalIndexSet" IndexPath="~/App_Data/TEMP/ExamineIndexes/Internal/">

      <IndexAttributeFields>

        <add Name="id" />

        <add Name="nodeName" />

        <add Name="updateDate" />

        <add Name="writerName" />

        <add Name="path" />

        <add Name="nodeTypeAlias" />

        <add Name="parentID" />

      </IndexAttributeFields>

      <IndexUserFields />

      <IncludeNodeTypes/>

      <ExcludeNodeTypes />

    </IndexSet>

    <!-- Removed internal umbraco indexer for clarity of post -->

</ExamineLuceneIndexSets>

ExamineSettings.Config

<ExamineSearchProviders defaultProvider="InternalSearcher">

    <providers>

      <add name="KBSearcher"

           runAsync="true"

           type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"

           analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net"  

           enableLeadingWildcards="true"

          indexSet="KBIndexSet" />

 

      <add name="InternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"

           analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"/>

 

      <add name="InternalMemberSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"  analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" enableLeadingWildcards="true"/>

    </providers>

  </ExamineSearchProviders>

 

In my class, i've got the following fields arrayed:

private string[] searchArrayGeneral = new string[] { "articleTitle", "articleType", "symptoms", "nodeName", "pageTitle", "bodyText", "search", "product", "category", "purpose", "resolution", "additionalinformation", "keywordsToSearchUpon"};

 Method called to generate the results

 private void SearchSiteGeneral()

        {

            var criteria = ExamineManager.Instance.

                            SearchProviderCollection["KBSearcher"]

                            .CreateSearchCriteria(UmbracoExamine.IndexTypes.Content);

            var filter = criteria

                         .GroupedOr(searchArrayGeneral, SearchTerm.MultipleCharacterWildcard())

                         .Not()

                         .Field("umbracoNaviHide", "1")

                         .Compile();

            SearchResults = ExamineManager.Instance.SearchProviderCollection["KBSearcher"].Search(filter);

            SearchResultListing.DataSource = SearchResults;

            SearchResultListing.DataBind();

        }

Output string from filter when searching for 'How To'

{ SearchIndexType: content, LuceneQuery: +(+(articleTitle:how to* articleType:how to* symptoms:how to* nodeName:how to* pageTitle:how to* bodyText:how to* search:how to* product:how to* category:how to* purpose:how to* resolution:how to* additionalinformation:how to* keywordsToSearchUpon:how to*) -umbracoNaviHide:1) +__IndexType:content }
