Stopwords

Stopwords are common words that are filtered out during search queries because they typically do not contribute to meaningful search results. By omitting words like “the,” “is,” or “an” from search indexing, Experro improves search efficiency and relevance by allowing the engine to focus on more significant keywords.Example:
In an online apparel store, excluding stopwords ensures that a query like “the red dress” is interpreted simply as “red dress,” returning a more accurate list of relevant products.

Use-Cases

Improving Search Efficiency:
Filtering out stopwords enables the search engine to focus on more meaningful terms, leading to faster and more relevant search results.
Reducing Noise:
Eliminating common, irrelevant words reduces search result noise, resulting in more precise product matches.

By managing stopwords effectively in Experro, you can significantly enhance the precision and efficiency of search results, ensuring that users find exactly what they’re looking for.

Spellcheck

The Spellcheck feature in Experro is designed to correct common misspellings in search queries, ensuring that users find the products they are looking for. By leveraging AI-based backend processes, Spellcheck maps frequently misspelt terms to their correct forms. This means that even when users make errors while typing, the search engine can automatically adjust the query and return accurate, relevant results. All you need to do is specify the commonly misspelt terms on the portal, and the system will recognize these terms as valid search queries rather than errors.For Example: If a user types “cher” while looking for a chair, the system automatically corrects the query to “chair,” ensuring that the correct product listings are returned. Administrators simply need to add “cher” in the Spellcheck configuration, and the term will be recognized as the intended search term.

Use-Cases

Correcting Misspellings:
For instance, if a user searches for “cher” instead of “chair,” the Spellcheck feature corrects the query to display results for “chair.”
Improving Search Accuracy:
By correcting misspelt terms, the search engine provides more accurate and relevant results, thereby enhancing the overall search experience.

The underlying AI engine may dynamically learn from user behavior to enhance these corrections, but the administrative entries ensure that common misspellings are preemptively addressed.

Stemming

Stemming is the process of reducing words to their root or base form, ensuring that different variations of the same word (e.g., “run,” “running,” “ran”) are treated as equivalent. This unified treatment helps to deliver consistent and comprehensive search results, regardless of the word form used by the customer.By applying stemming, Experro enhances search accuracy and ensures that users find relevant results even when they use different tenses or word forms.

Use-Cases

Handling Different Tenses:
If users search for “running” or “ran,” stemming ensures that the base term “run” is also considered, resulting in unified search results.
Improving Search Relevance:
Recognizing and grouping different forms of a word allows the search engine to return a broader set of relevant results, thereby improving overall search accuracy.

Example:
In a sports apparel store, configuring stemming for the term “run” ensures that a search for “running shoes” or “run shoes” displays the same relevant products.

Typically, the system uses the base term to automatically generate or recognize its variations. While only one term can be added per entry, Experro’s stemming algorithm processes related forms of the word to ensure that searches return unified and relevant results.

By carefully configuring and managing stemming alongside other dictionary features—such as Stopwords and Spellcheck—you can significantly improve the accuracy and efficiency of your search functionality in Experro, ultimately enhancing the overall user experience.
