UmbracoExamine.PDF
PDF indexing support in UmbracoExamine using PdfPig
Installation
Install with Nuget:
Install-Package UmbracoCms.UmbracoExamine.PDF
You will then have a new Examine index called "PDFIndex" available.
Multi index searchers
To use the MultiSearcher in V8, you can instantiate it when needed like:
using(var multiSearcher = new MultiIndexSearcher("MultiSearcher", new IIndex[] {
externalIndex,
pdfIndex
}))
{
...
};Or you can register a multi-index searcher with the ExamineManager on startup like:
[ComposeAfter(typeof(ExaminePdfComposer))] //this must execute after the ExaminePdfComposer composer
public class MyComposer : ComponentComposer<MyComponent>, IUserComposer
{
}
public class MyComponent : IComponent
{
private readonly IExamineManager _examineManager;
public MyComponent(IExamineManager examineManager)
{
_examineManager = examineManager;
}
public void Initialize()
{
//Get both the external and pdf index
if (_examineManager.TryGetIndex(Constants.UmbracoIndexes.ExternalIndexName, out var externalIndex)
&& _examineManager.TryGetIndex(PdfIndexConstants.PdfIndexName, out var pdfIndex))
{
//register a multi searcher for both of them
var multiSearcher = new MultiIndexSearcher("MultiSearcher", new IIndex[] { externalIndex, pdfIndex });
_examineManager.AddSearcher(multiSearcher);
}
}
public void Terminate() { }
}With this approach, the multi searcher will show up in the Examine dashboard and it can be resolved from the ExamineManager like:
if (_examineManager.TryGetSearcher("MultiSearcher", out var searcher))
{
//TODO: use the `searcher` to search
