In traditional lexical search we often use text analysis to improve search results. OpenSearch uses analyzers to refine, tokenize, and convert text fields before storing them in an index. As an example, indexing <p><b>Actions</b> speak louder than <em>words</em></p> can result in the following indexed tokens: [action, speak, loud, word]. The behavior depends on the analyzers you define for your text fields.
