With the full-text search you get results from search engines that contain exactly the complete phrase you are looking for.
What can the full text search be used for?
In a normal search, search engines ignore stop words such as definite and indefinite articles, connective words and special characters. In the context of the full-text search, on the other hand, the full text is indexed, which also contains all stop words. This enables you to search for complete phrases or quotations. If you are looking for a specific phrase, you must put it in quotation marks.
Example for the full text search
Let’s assume you enter the phrase “cold-pressed olive oil from Tuscany” in the search field. The full text search only lists websites that contain the entire wording. The normal search would also list pages that only contained “olive oil” and “extra virgin olive oil”.
According to lawfaqs.net, a full text search can only be carried out by full text search engines. This includes, for example, Google.
Difference between full text search and meta search
In contrast to the full text search, there is a meta search. Here the meta fields of documents are searched by a meta search engine. In numerous areas, the content of the document can be made accessible by searching through the meta title, meta description and meta keywords. The basic requirement for this is that all meta data have been entered correctly and completely. Another big difference to the full text search is that the meta search analyzes a smaller amount of text and is therefore faster.
However, the full text search is more reliable than the meta search. Here the documents are completely analyzed. Thanks to this detailed analysis, a search engine can work more precisely, since the keyword density and its distribution are automatically calculated during the search. The search results are also sorted based on these factors. The searcher not only receives all results for the term he is looking for, but they are already sorted according to relevance. There is therefore a higher probability that one of the first hits in the search will also contain the desired document.
Where is the full text search usually carried out?
Google is without a doubt the most popular search engine that carries out full-text searches. This works with the help of the Googlebot, which constantly scans the Internet for new and changed websites. After a document has been read, the information is stored in its index and further links are followed. This is how Google finds websites that were not previously in the Google index.
User-oriented search engines
Over the years, the added value for the user has become more and more important. Numerous full-text search engines are now paying more attention to added value for the user in the text at hand.
