In the Optimizely Search & Navigation admin view, administrators can set a relative weight of different properties (title, content, summary, or attached document content) with the [Unified Search](docId\:Zk9jo_BnvtkTuJ6yH4qiH) object. The default property weight, 1, does not affect the score. A weight above 1 boosts the score if the information is in a corresponding property. A weight smaller than 1 reduces the score.

## UnifiedSearchFor weight value

The `IClient` `UnifiedSearchFor` extension method is in the `EPiServer.Find` namespace that enables search using administrator-defined weight values. For example, searching for *Beethoven* with weights:

```csharp
var results = client.UnifiedSearchFor("Beethoven").GetResult();
```

Searching for *Beethoven* with weights and *Swedish* applied for stemming:

```csharp
var results = client.UnifiedSearchFor("Beethoven", Language.Swedish).GetResult();
```

In addition, `UnifiedSearchFor` extension methods for `IClient` (in the `EPiServer.Find.Cms` namespace) take a search query as a parameter. The language used for stemming is selected automatically (based on `EPiServer.Globalization.ContentLanguage.PreferredCulture`), and the culture for stemming mappings is defined in the `episerver.find` section in `app.config/web.config`. The following sample searches for *Beethoven* with weights and the automatically selected stemming language.

```csharp
var results = client.UnifiedSearchFor("Beethoven").GetResult();
```

## UsingUnifiedWeights weight value

Another option is to use the `UsingUnifiedWeights` extension method for `IQueriedSearch` from `EPiServer.Find` namespace. The following example shows how to search for *Beethoven* with weights and *English* applied for stemming:

```csharp
var result = client.UnifiedSearch(Language.English).For("Beethoven").UsingUnifiedWeights().GetResult();
```

The `UsingUnifiedWeights` extension method takes a `UnifiedWeightsValues` parameter, which lets you specify weights when searching. Here is a sample of searching for *Beethoven* with specific weights and *English* applied for stemming:

```csharp
var weights = new UnifiedWeightsValues() {
  SearchTitle = 2.0,
    SearchText = 1.5,
    SearchSummary = 1.0,
    SearchAttachment = 0.5
};

var result = client.UnifiedSearch(Language.English).For("Beethoven").UsingUnifiedWeights(weights).GetResult();
```

In the above sample, hits for which *Beethoven* appears in the title are the most important and should display at the top of search results. It also boosts hits that contain *Beethoven* in the body, but having *Beethoven* in an attached document's content is less important.
