Answer 1

Examine is a Lucene implementation for Umbraco.
Taken from the Umbraco documentation, the following steps should help you get going with searching with Examine and Umbraco:
Create an index
To create a searchable index we need to create 3 things: an Indexer a Searcher and an Index Set.
Open ~/Config/ExamineSettings.config and add an indexer under the 'ExamineIndexProviders/providers' section (in this example it is named ExternalIndexer):
<add name="ExternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"/>
In the same file (~/Config/ExamineSettings.config) add a searcher under the 'ExamineSearchProviders/providers' section (in this example it is named ExternalSearcher):
<add name="ExternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine" />
In the same file we'll change the default search provider to the one we've created, set defaultProvider="ExternalSearcher"
Open ~/Config/ExamineIndex.config and add an index set (in this example it is named ExternalIndexSet):
<IndexSet SetName="ExternalIndexSet" IndexPath="~/App_Data/TEMP/ExamineIndexes/External/" />
We have a searchable index configured using Examine. Examine will detect that the index doesn't exist on the file system yet so the index will be rebuilt during application startup. Once that happens the index will automatically stay up to date with the data in Umbraco.
Searching with Razor
In razor macros there's a Search method on the DynamicNode model which will return a DynamicNodeList:
#if (!string.IsNullOrEmpty(Request.QueryString["query"]))
{
<ul>
#foreach (var result in Umbraco.Search(Request.QueryString["query"]))
{
<li>
#result.Name
</li>
}
</ul>
}
