Text search is a method used to find specific words or phrases within a body of text. This technique is commonly employed in search engines, databases, and document management systems to help users quickly locate relevant information. By indexing the text, these systems can efficiently retrieve results based on user queries. In many applications, text search can include features like keyword highlighting, fuzzy matching, and filtering options. These enhancements improve the user experience by making it easier to navigate large volumes of data. Popular tools for text search include Elasticsearch, Apache Solr, and built-in functions in software like Microsoft Word.
