The former case is the simple one: the value() of the %LiteralTerm will simply be compared to the value of the ComparisonTerm.property(). In the latter case value() will be matched to rdfs:label of any resource. So in essence the following two examples are equal: </p> <p> <pre class="fragment"> ComparisonTerm( Vocabulary.NAO.hasTag(), LiteralTerm("nepomuk") ); ComparisonTerm( Vocabulary.NAO.hasTag(), ComparisonTerm( Vocabulary.RDFS.label(), LiteralTerm("nepomuk") ) ); </pre> </p> <p> <b>Usage as "stand-alone" term </b> </p> <p> As a term by itself %LiteralTerm will act like a traditional full text query and match all resources that contain the string value in some property. </p> <p> <pre class="fragment"> LiteralTerm( "nepomuk" ); </pre> </p> <p> The example above will match all resources that have a property with a value containing the string "nepomuk". </p> <p> <b>Examples </b> </p> <p> <pre>LiteralTerm("nepomuk")</pre> searches for the term "nepomuk". </p> <p> <pre>LiteralTerm("'nepomuk*'")</pre> searches for the terms starting with "nepomuk". </p> <p> <pre>LiteralTerm("'nepomuk kde'")</pre> searches for the term "nepomuk kde". </p> <p> <pre>LiteralTerm("'nepomuk* kde'")</pre> searches for terms matching "nepomuk* kde". </p> <p> %LiteralTerm always tries to normalize the query terms as best as possible. This includes automatically adding quotes as needed. </p> <p> <dl class="warning" compact><dt><b>Warning:</b></dt><dd> Be aware that the examples above apply to using %LiteralTerm as a stand-alone term or in a ComparisonTerm.Contains term. When using ComparisonTerm.Regexp the test as specified will be used as-is to create the regular expression. </dd></dl> </p> <p> <dl class="author" compact><dt><b>Author:</b></dt><dd> Sebastian Trueg
