With Optimizely Configured Commerce's Commerce Search v2 (Elasticsearch v7), you can use the Dimensional Analyzer to search products by product size with search terms containing the size and unit of measurement. The Dimensional Analyzer also supports searching product sizes with search terms containing fractional number sizes.

## Configure the Dimensional Analyzer

1. Identify the product attribute or the custom product property with the product size information.
2. Go to **Admin Console** > **Marketing** > **Search** > **Field Boosting**.
3. Select and edit the product size attribute or custom property.
4. Toggle **Queryable** to **Yes**.
5. Select **Text** for the Data Type.
6. Select **IscDimensionalAnalyzer** as for **Index Analyzer** and **Query Analyzer**.
7. Keep default Boost Value of 1 or increase the Boost Value to boost search results relevancy when searching by size.
8. Click **Save**.

## Product size data and search terms

Fill in the Product Size field or attribute with size and unit of measurement data for indexing and querying. Some examples of product sizes and search terms that match the product size are listed in the following table. You can find a full list of supported standard fractions and measurement units and their equivalent mapped synonyms in the Configured Commerce code under the `Insite.Search.ElasticsearchV7.TokenFilters` namespace with names `IscDimensionalTokenFilter` and `IscFractionalTokenFilter`.

| **Product Size** | **Search Terms**                               |
| ---------------- | ---------------------------------------------- |
| 1/2 in           | 1/2 in, 0.5in, 0.5", .5", 1/2 inch, 1/2 inches |
| 1 1/2 ft         | 1-1/2 ft, 1 1/2ft, 1.5ft, 1.5', 1-1/2 feet     |
| 1/4 oz           | 1/4 oz, 1/4 ounce, 0.25 oz, .25ounces          |
| 2.25 gallon      | 2-1/4 gal, 2.25gallons                         |
| 1/32 quart       | 1/32 qt, 0.0313 quarts, 0.031qt, 0.03qt        |
| 27/32 cm         | 27/32cm, 0.8438 cm, 0.844cm, 0.84 centimeter   |

## Rebuild search index

Once you have updated the product size information, go to **Admin Console** > **Marketing** > **Search** > **Indexing**. Click **Rebuild All**, and wait until search indexing is complete.

## Recommended usage

Optimizely recommends the following actions for the most effective usage of the Dimensional Analyzer:

1. **Collaborate with a partner** – Work closely with your Optimizely Partner to configure and optimize the Dimensional Analyzer for your specific needs.
2. **Use multiple search terms** – Ensure that users can search with various terms, including product size, measuring unit, keywords from the product title or description, and product category names. Include these search terms in the product attributes or custom product properties.
3. **Use product attributes** – All product attributes are stored together on the Search Index and queried using the Filters field, which uses the default analyzer. For a product attribute, the search query uses the Dimensional Analyzer on the attribute and the Default Analyzer on the Filters field, which may result in more text matches.
4. **Use custom product properties** – For more precise size matches, store product size information and relevant keywords from the product title, description, and category names in a custom product property. Apply the Dimensional Analyzer to this property.
5. **Enhance search capabilities** – By following these steps, you can search for product sizes using more than two terms, such as combinations of size, product title, and product category name, making your searches more comprehensive and effective.
