## Maximize Search Quality

## Search Quality Overview
The search engine must first find and return the set of products in the catalog that match the intent expressed by a visitor in a search query. However, the search query often differs from how the product is described in the catalog. For example, a furniture catalog may contain ottomans but users may search for “footstools”. Or an apparel catalog contains “t-shirts”, but users may search for “tee”.
To handle such scenarios, the query is enhanced by referring to a list of synonyms. While we do recommend adding your own synonyms, the Bloomreach engine also maintains a robust synonym dictionary accumulated over the years based on queries entered across our customer base.
The query is then compared to the fields in your product catalog-- such as title, category, and other fields that you can designate to be "search-able" -- to find the relevant matches. In case there is no matching product found, the engine automatically correct any misspelled words and/or relax the query to one that returns a broader result set.
Once a set of products has been returned for a search query, Bloomreach adjusts the order of those products to optimize for higher expected revenue per visit (RPV) for the query. Several factors contribute to the algorithm that optimizes product ranking. A high-level explanation of the various signals is included below.
Once the relevant set of products is determined (referred to as the recall set), Bloomreach will adjust the order of those products to maximize site Revenue.
There are several factors involved in determining a product's rank in the recall set. A few of the most important signals are:
Product performance for a specific query or category,
Personalization - driven by a user's preferences determined through their site behavior, and
Relevance - based on Bloomreach's semantic understanding of the query and product.
