A word that is a synonym of another word using a thesaurus for example, the word "metal" can have synonyms such as "aluminum" and "steel". The columns can be of type char , varchar , nchar , nvarchar , text , ntext , image , xml , varbinary , or varbinary max. This parameter is optional.
If documents of different languages are stored together as binary large objects BLOBs in a single column, the locale identifier LCID of a given document determines what language to use to index its content. If no value is specified, the column full-text language is used. The hexadecimal value must not exceed eight digits, including leading zeros. If the language specified is not valid or there are no resources installed that correspond to that language, SQL Server returns an error.
An implicit conversion occurs when another character data type is used as input. Large string data types nvarchar max and varchar max cannot be used. Because "parameter sniffing" does not work across conversion, use nvarchar for better performance.
In the example, declare SearchWord as nvarchar Some languages, such as those written in some parts of Asia, can have phrases that consist of one or more words without spaces between them. Phrases should be enclosed in double quotation marks "". The search for characters in the word or phrase is not case-sensitive. Noise words or stopwords such as a, and, or the in full-text indexed columns are not stored in the full-text index.
If a noise word is used in a single word search, SQL Server returns an error message indicating that the query contains only noise words.
Punctuation is ignored. Failure to find it would be expensive. The asterisk matches zero, one, or more characters of the root word or words in the word or phrase. Stemmer behavior is defined based on stemming rules of each specific language. The neutral language does not have an associated stemmer. The column language of the columns being queried is used to refer to the desired stemmer. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
You must specify two search terms. A given search term can be either a single word or a phrase that is delimited by double quotation marks " phrase ". Chained proximity terms must all be in the document for a match to be returned.
For example, if a document contains the sentence, "The fox ate the chicken," its ranking would be high because the terms are closer to one another than in other documents.
Specifies a match of words or phrases, and optionally, the maximum distance allowed between search terms. Every specified term must be in the document for a match to be returned. If it isn't, then only the first form is available. The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan. Having run both queries on a SQL Server instance, I can confirm the first query was fastest in my case.
The former will find records with values like " this is a test " and " a test-case is the plan ". The latter will also find records with values like " i am testing this " and " this is the greatest ". Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Contains field, "Butter" - will return only results where Butter is a word - contains is case insensitive. A word or phrase. The prefix of a word or phrase. A word near another word. A word inflectionally generated from another for example, the word drive is the inflectional stem of drives, drove, driving, and driven.
