Semantic search stored procedures in SQL Server enable you to register and unregister a pre-populated Semantic Language Statistics database. Fulltext has to be enabled for this to work. To index office 2010 documents, filter packs are available.
User interface with a clean search page that lets users search for entities based on full-text can be built with a full text stored procedure. When full-text is enabled, the queries can specify contains or full-text to return the results. Full text indexing services runs separately and can be expected to be up to date with all changes to the domain objects. Hence the full text stored procedure merely needs to execute a full-text query. The reason we want to store the query in a procedure is because it will give better performance and security. This is especially relevant when the search page is vulnerable to SQL injection attacks.
When the search page uses form to query against one or more fields of domain entities, then there are patterns we can use with service calls or ORM queries or database queries. Some pattern are for example when searching for a name and a SSN, the UI could build the predicate in the context of the domain entity selected on the screen. Another pattern is to query against one or more entities based on common attributes. The goal with the patterns is to classify and streamline the different access patterns to the data. Sometimes a materialized view helps, other times, the ORM may have methods to lookup entities via some top level domain entity.
Search page presentation can be dedicated page or inset into various other pages. Search Results should be accordingly presented.
