Examine allows you to index and search data easily and wraps the Lucene.Net indexing/searching engine. Lucene is super
fast and allows for very fast searching even on very large amounts of
data. Examine is provider based so is very extensible and allows you to
configure as many indexes as you like and each may be configured
individually. Out of the box our UmbracoExamine library that is shipped with Umbraco gives you Umbraco based implementations for indexers and searchers to get started quickly.
Configuration:
Step 1: Open
the ‘ExamineSettings.config’ file
from the ‘config’ folder.
Step 2: Create
a new Index Provider in the ExamineIndexProviders section:
<add name="MyIndexer" type="UmbracoExamine.UmbracoContentIndexer,
UmbracoExamine"/>
Step 3: Create
a new Search Provider in the ExamineSearchProviders section:
<add name="MySearcher" type="UmbracoExamine.UmbracoExamineSearcher,
UmbracoExamine"/>
Step 4: Open
the ‘ExamineIndex.config’ file from
the ‘config’ folder.
Create a new Index Set in the ExamineLuceneIndexSets section:
<IndexSet SetName="MyIndexSet" IndexPath="~/App_Data/TEMP/MyIndex" />
Code:
@using
Examine;
@{
var searchTerm =
Request.QueryString["search"];
}
<ul class="search-results">
@foreach
(var result in ExamineManager.Instance.Search(searchTerm, true))
{
<li>
<span>@result.Score</span>
<a href="@umbraco.library.NiceUrl(result.Id)">
@result.Fields["nodeName"]
</a>
</li>
}
</ul>
