What basic relevance features does Acquia Search powered by SearchStax offer to improve search results?

Acquia Search powered by SearchStax provides several basic relevance features, including managing stop words and adjusting the relevance of search results:

• Stop words are common words that add no value to search queries. You can omit them to improve search accuracy.
• Administrators can adjust the weights of different fields to optimize the relevance of search results. For example, if a match occurs in the title field, administrators can decide whether to give that more or less weight compared to other fields such as description.
