The results are the same as if you simply used the AND operator. In a SQL Server 2008 proximity search predicate (CONTAINS, FREETEXT), the NEAR operator is mapped internally to the AND operator. The order in which the phrases appear within the search document are irrelevant to a proximity search. SQL Server uses a vector-space search algorithm to perform proximity searches. There is currently no method for specifying a user-defined proximity (i.e., '10 words apart', '2 paragraphs apart', etc.) The more intervening words between the two search terms, the lower the total rank. The number of intervening words between phrases is factored into the rank of documents containing both of the search words or phrases. Note that paragraph breaks and other non-space whitespace can affect the calculation of the number of intervening words, though the specifics have not been published by Microsoft. In SQL Server 2008 words are considered to be 'near' when they are within 50 words of one another in prior versions of SQL Server search words or phrases were considered 'near' one another with slightly over 1,100 intervening words. This is achieved by using the keyword 'NEAR' (or the operator '~') between two given search words or phrases. The algorithms used to calculate rank include Jaccard for weighted searches and OKAPI BM25 for FREETEXT searches.įull-text searching has the ability to find words and phrases that are located in close proximity to one another. * User-defined weights - user-defined weights are factored into rank when the ISABOUT weighted search operator is used * Proximity of search words/phrases in proximity search - proximity is factored into rank when the NEAR proximity search operator is used * Number of occurrences of search words/phrases - the more times the search words/phrases occur in the document, the higher the ranking * Document length - longer documents are generally considered more relevant A variety of factors are considered in the various ranking algorithms used, including: Although rank is always calculated internally when a full-text search is performed, it is only exposed through the use of the full-text search functions. The higher the value the more relevant the match. The rank is a number from 0 to 1000 that indicates the relevance of the search result. The functionality of these predicates and functions are listed in the following table: T-SQL supports two predicates and two functions that can be used to perform full-text searches: CONTAINS, CONTAINSTABLE, FREETEXT, and FREETEXTTABLE. The primary key of the table is on the column 'id' There exists a prior full-text index on the column 'notes'. Inside this table you will find the following column names: This table contains information about various athletes their events and results in the Olympic Games.

These examples refer to an imaginary table called 'Athletes'.

The following article contains SQL code and simple worked examples. įull text indexes must be populated and are stored inside full-text catalogues.Searching is installed as a separate service called MSSearch, an optional component of SQL Server 7.0/2000/2005. It is a powerful and fast way of referencing the contents of almost any character-based column on SQL Server 2000, SQL Server 2005, and SQL Server 2008.

Is there anything I can do? It used to be so simple to search for items on XP, now I can't search for anything.SQL Server Full Text Search is an inexact string matching technology for SQL Server. I have tried troubleshooting but it tells me there are no errors.

When I go to file explorerĪnd search through search options nothing comes up. I have rebuilt the index several times but nothing changes. I have gone through indexing options as instructed but nothing works. When I use that search bar on the bottom left it does not return any resultsĮven when I filter by document Even when I know the file name of the document it does not show up. I have contacted Microsoft but cannot seem to get this issue resolved.

I am unable to search for files either by name or more importantly within a file on my Windows 10 computer. I used to be able to search for files by using the 'search a word or phrase in a document' feature that was available in windows XP. I bought a new laptop with Windows 10 and downloaded Office about a year ago, my previous laptop had windows XP.
