Bobo-Browse.Net
===============
This Bobo-Browse.Net is build for Lucene.Net 3.x.
if you still use Lucene.Net 2.x,you can see this project BoboBrowse.Net(https://bobo.codeplex.com/).
###Building the Source###
Prerequisites:
- [.NET Framework 3.5 SP1](http://www.microsoft.com/en-us/download/details.aspx?id=25150)
- [.NET Framework 4.0.x](http://www.microsoft.com/en-us/download/details.aspx?id=17851)
- [.NET Framework 4.5.x](http://www.microsoft.com/en-us/download/details.aspx?id=42643)
- [Windows PowerShell](http://technet.microsoft.com/en-us/library/hh847837.aspx)
> NOTE: If you have not yet run Windows Powershell on your computer, you will need to run the following command from an elevated command prompt before you can build the source.
```
Set-ExecutionPolicy RemoteSigned
```
To build the source, run the following command from the root directory of the Git project (the same directory that contains the .git folder):
```
build.bat -v:1.1.1 -pv:1.1.1-alpha00006
```
The -v parameter is the file version number, and the -pv parameter is the NuGet package version number. The package version number can contain a pre-release tag as shown in the example, but is not required.
Once the source has been built, you can install Bobo-Browse.Net into your project using NuGet. In Visual Studio, open the Options dialog from the Tools menu. In the left pane, choose NuGet Package Manager > Package Sources. Click the "+" button. Name the package source "Local Bobo-Browse.Net Feed", and add a Windows file path to `[Bobo-Browse Project Directory]\packages\packagesource\`. You can then use either the UI or Package Manager Console to install Bobo-Browse.Net into your project by selecting the "Local Bobo-Browse.Net Feed" as the package source.
###Performance###
we recommend use a **singleton pattern** to create one instance of BoboBrowser in the application and interval update object in the background-thread.that can avoid frequency reload entity index file and reduce a memory usage.
```cs
public void TestSimpleBrowser()
{
var query = new TermQuery(new Term("name", "asp.net"));
Console.WriteLine(string.Format("query: <{0}>", query.ToString()));
var request = new BrowseRequest()
{
Count = 10,
Offset = 0,
Query = query,
Sort = new Sort(new SortField("price", SortField.DOUBLE,false)).GetSort()
};
var faceHandlers = new FacetHandler[] { new SimpleFacetHandler("category") };
var browser = new BoboBrowser(BoboIndexReader.GetInstance(IndexReader.Open(_indexDir, true), faceHandlers));
var factSpec = new FacetSpec() { OrderBy = FacetSpec.FacetSortSpec.OrderHitsDesc, MinHitCount = 1 };
request.SetFacetSpec("category", factSpec);
var result = browser.Browse(request);
Console.WriteLine(string.Format("total hits:{0}", result.NumHits));
Console.WriteLine("===========================");
foreach (var facet in result.FacetMap["category"].GetFacets())
{
var category = _categories.First(k => k.Value == int.Parse(facet.Value.ToString()));
Console.WriteLine("{0}:({1})", category.Key, facet.HitCount);
}
Console.WriteLine("===========================");
for (var i = 0; i < result.Hits.Length; i++)
{
var doc = browser.Doc(result.Hits[i].DocId);
var category = _categories.First(k => k.Value == int.Parse(doc.GetField("category").StringValue)).Key;
Console.WriteLine(string.Format("{2} - {0} ${1} by {3}", doc.GetField("name").StringValue, doc.GetField("price").StringValue, category, doc.GetField("author").StringValue));
}
}
```
output:
```
total hits:6
