Our.Umbraco.SearchSpellCheck

A Lucene.Net-based spell checker for Umbraco v8 and v9.

NuGet release Build Status

This project wouldn't exist without Lars-Erik Aabech who created a v7 version of this, which a lot of the work is based on.

How it works

alt text

On startup, this extension will index all the content in your site based on the IndexedFields settings. On every search, the extension will check the multi-word search term against the index and suggest the most likely words to the user.

Installation

At present, the only way to install this is to use NuGet. You can find the package on NuGet.org and install it using the Package Manager UI in Visual Studio.

Configuration

v9

In v9 you'll need to use the appSettings.json file instead of the web.config file.

{
    "SearchSpellCheck": {
        "IndexName": "SpellCheckIndex",
        "IndexedFields": [ "nodeName" ],
        "BuildOnStartup": true,
        "RebuildOnPublish": true,
        "AutoRebuildIndex": false,
        "AutoRebuildDelay": 5,
        "AutoRebuildRepeat": 30,
        "EnableLogging": false
    }
}

v8

When the package is installed, new keys will be added to the appSettings section of your web.config:

<add key="Our.Umbraco.SearchSpellCheck.IndexName" value="SpellCheckIndex" />
<add key="Our.Umbraco.SearchSpellCheck.IndexedFields" value="nodeName" />
<add key="Our.Umbraco.SearchSpellCheck.BuildOnStartup" value="true" />
<add key="Our.Umbraco.SearchSpellCheck.RebuildOnPublish" value="true" />
<add key="Our.Umbraco.SearchSpellCheck.AutoRebuildIndex" value="false" />
<add key="Our.Umbraco.SearchSpellCheck.AutoRebuildDelay" value="5" />
<add key="Our.Umbraco.SearchSpellCheck.AutoRebuildRepeat" value="30" />
<add key="Our.Umbraco.SearchSpellCheck.EnableLogging" value="false" />

Settings

IndexName: The name of the Lucene index to be created. This is the also name of the folder in the App_Data folder that contains the Lucene index. By default it is SpellCheckIndex but this can be changed if you need a different naming convention.

IndexedFields: The alias(es) of fields to be indexed. This is a comma-separated list of field names. By default only the nodeName field is indexed. Currently, there is support for textstring, textareas, TinyMCE, Grid Layout and Block List Editor fields.

BuildOnStartup: Boolean indicating if you want the index to be populated on startup. Defaults to true.

RebuildOnPublish: Boolean indicating if you want the index to be populated on content being saved and published successfully. Defaults to true.

AutoRebuildIndex: Boolean indicating if you want a background process to run to rebuild the index. Defaults to false.

AutoRebuildDelay: Number of minutes you want to delay the background process from starting. Defaults to 5 minutes.

AutoRebuildRepeat: Number of minutes you want the scheduled background process to run. Defaults to 30 minutes.

EnableLogging: Useful if you want to see what properties are being indexed and the content that is returned from the index. Defaults to false.

Usage

v9

The package enables a SuggestionService to be injected in v9:

private readonly IExamineManager _examineManager;
private readonly ISuggestionService _suggestionService;

public SearchService(IExamineManager examineManager, ISuggestionService suggestionService)
{
    _examineManager = examineManager;
    _suggestionService = suggestionService;
}

public string GetSuggestions(string searchTerm)
{
    return _suggestionService.GetSuggestion(searchTerm, accuracy: 0.25f);
}

Which could in turn be returned in a view component:

if (model.TotalResults == 0)
{
    model.SpellCheck = _searchService.GetSuggestions(model.SearchTerm);
}

And then returned in the view:

@if (!string.IsNullOrEmpty(Model.SpellCheck))
{
    <p>Did you mean <a href="?s=@Model.SpellCheck"><em>@Model.SpellCheck</em></a>?</p>
}

v8

The package is a single class called Our.Umbraco.SearchSpellCheck.Suggestions.

Within a SearchService, you could use the Suggestions class to get suggestions for a given word:

public string GetSuggestion(string searchTerm)
{
    return Suggestions.GetSuggestion(searchTerm);
}

This could then be returned within a ViewModel:

if (!string.IsNullOrEmpty(viewModel.SearchTerm))
{
    viewModel.SpellCheck = _searchService.GetSuggestion(viewModel.SearchTerm);
}

And then in your view:

@if (Model.TotalResults == 0 && !string.IsNullOrEmpty(Model.SpellCheck))
{
    @:Did you mean <em><a href="?q=@Model.SpellCheck">@Model.SpellCheck</a></em>?
}
