This is not too surprising considering there was a five-year gap between these major SQL Server 2008 is not as much of a quantum leap forward from SQL Server 2005 | 2024 CHAPTER 50 SQL Server Full-Text Search Here are some examples using FREETEXT and FREETEXTTABLE Use AdventureWorks SELECT from where Freetext Barack Obama Corrected HPC Use AdventureWorks SELECT FROM as s JOIN SELECT key rank FROM FREETEXTTABLE jon 100 AS k ON k. key order by rank desc Notice that the FREETEXTTABLE example does the functional equivalent of a CONTAINSTABLE query because the search is wrapped in double quotation marks. Stop Lists Stop lists are used when you want to hide words in searches or to prevent from being indexed those words that would otherwise bloat your full-text index and might cause performance problems. Stop lists also known as noise word lists or stop word lists are a legacy component from decades ago when disk prices were very expensive. Back then using stop lists could save considerable disk space. However with disk prices being relatively cheap the use of stop lists is no longer as critical as it once was. You can create your own stop word list by expanding your database in SSMS and then right-clicking on the Full-Text Stoplists node and selecting New Full-Text Stoplist. You have an option of creating your own stop list basing it on a system stop list creating an empty one or creating one based on another stop list in a different database. Each catalog can have its own stop list which is a frequently demanded feature because some search consumers want to be able to prevent some words from being indexed in one table but want those words indexed in a different table. After you create a stop word list you can maintain it by right-clicking on it in the Full-Text Stoplists node and selecting Properties. Figure illustrates this option. The options are to add a stop word delete a stop word delete all stop words and clear the stop list. After selecting the option you want you can enter a stop word and the language in which you want that stop word to be applied. Keep in mind
