- 5. Keyword Query SyntaxUsed to search by Managed PropertiesCan specify Scopes (Scope:”MyScope”)Does not support wildcard searchAND implied between each keyword (i.e.: Color:”Red” Size:”M” is the same Color=“Red” AND Size=“M”)OR implied when multiple keywords of the same managed property used (i.e.: Color:”Red” Color:”Blue” translates to Color=“Red” OR Color=“Blue”)Can Specify Content Sources (ContentSource:”My Source”IsDocument:”1” – Query Documents Only
- 6. URL SyntaxSearch Center and RSS pages accept queries via the query stringUses the keyword syntax specified on the K parameter (i.e.: results.aspx?k=Accounting)Can specify scope using the S parameter (i.e.: results.aspx?k=Account&s=Corporate Documents)Results can be paged with the start parameter
- 7. KeywordQuery ClassSharePoint API class to execute a query using Keyword SyntaxReturns a ResultsTableCollection object which can be converted to a DataTableCan only be used on the SharePoint serverUses the credentials of the application executing the code (i.e.: the user who ran a console application, or the application pool account)SelectProperties can be used to add custom managed properties. You must add all default properties as well as your own custom properties if this is used.
- 8. Full Text SQL SyntaxT-SQL style method of querying Enterprise SearchCan be used to do a wildcard searchSpecify columns in SELECT statement SELECT Title, Path, Write, Rank,…Always FROM Scope()Note syntax when using WHERE with a ScopeWHERE “Scope” = ‘File Share’CONTAINS predicate supports wildcard search, FREETEXT does notORDER BY clause can be used for orderingSee Office Server SDK for more information
- 9. Web ServicesLocated on your SharePoint server in the _vti_bin virtual folder/_vti_bin/search.asmx – Enterprise Search web service/vti_bin/spsearch.asmx – WSS3 Search web serviceBoth use the same syntaxWeb Service requires authenticationSpecify using .Credentials propertyRequires an input XML stringQuery method returns an XML stringQueryEx method returns a DataSet
- 10. Query Request SchemaCan use Keyword Query syntax or Full Text SQL Query syntaxQueryText element contains the querytype=“STRING” – Keyword Querytype=“MSSQLFT” – Full Text SQL QueryRange / StartAt/ Count elements can be used for pagingProperties element can be used to specify custom managed properties when using Keyword Query syntaxSortByProperties element sorts keyword queriesNote the casing of everything
